A freeware Mac screensaver that will run AD modules.</div><div></div><div>MAD - More After Dark, a commercial pack of extra AD modules from BS.</div><div></div><div>ST - Star Trek: the Screensaver, a commercial AD package and modules from BS.This FAQ answers common questions about screensavers for the Macintosh. What's</div><div></div><div>available and whether or not you need a screensaver are covered. Most of this</div><div></div><div>FAQ pertains to the most popular commercial Macintosh screensaver - AD from BS,</div><div></div><div>and the modules available for it.This FAQ is crossposted to most of the comp.sys.mac.* newsgroups on an irregular</div><div></div><div>basis whenever it is updated. A copy can always be found on</div><div></div><div>
sumex-aim.stanford.edu in info-mac/gui/ad.The FAQ details common AD problems and misconceptions, concentrating on 'Why</div><div></div><div>does AD crash my machine?' The answer is almost always 'You need to get and run</div><div></div><div>the free 2.0x updater' or 'You are using a badly-written third-party module</div><div></div><div>running under the MultiModule or Randomizer modules'. [These modules impose</div><div></div><div>stricter rules on how a module can run than AD alone does, and a large number of</div><div></div><div>third party (shareware/freeware) modules either won't run as a sub-module or</div><div></div><div>crash the Macintosh.]</div><div></div><div>How to update AD is given in (1.0). A list of 'problem' modules that should not</div><div></div><div>be run under MultiModule/Randomizer is given in (5.0).The information in this FAQ is based on my use of AD and tidbits I have gleaned</div><div></div><div>from email from writers and users of third-party AD modules and with BS. I have</div><div></div><div>no connection with BS other than as a user of AD and MAD. (I'm declaring the</div><div></div><div>free T-shirt they gave me, though. Nothing underhand here.)I welcome comments and corrections, hints on using specific AD modules, and tips</div><div></div><div>and compatibility information relating to other Mac screensavers.This FAQ does not cover the use of AD on the Windows platform - it's for the Mac</div><div></div><div>version (and other Mac screensavers) only. There is no way to convert Windows AD</div><div></div><div>modules to Mac AD modules without extensive rewriting of the source code - it's</div><div></div><div>a job for the authors of that module, and few have experience of programming</div><div></div><div>Windows AND the Mac. Module ports are unlikely. Windows users should look at</div><div></div><div>'Intermission', a freely-available application that runs Windows AD modules.DO I NEED A SCREENSAVER? (0.0)</div><div></div><div>Despite what many people will tell you, the answer is almost certainly 'no'. It</div><div></div><div>takes a long time to burn the phosphor on a cathode ray tube with a still image</div><div></div><div>- accidentally leaving your Mac on all weekend won't do it, so don't worry if</div><div></div><div>you did this.</div><div></div><div>Old Mac Plusses or monochrome Mac monitors that have seen years of service may</div><div></div><div>have a ghostly bar at the top of the screen from the menu bar, visible when a</div><div></div><div>menu bar is not present, but that's about it.</div><div></div><div>The phosphor on colour monitors is even more difficult to burn, making</div><div></div><div>screensavers even less useful than you may think.</div><div></div><div>Running a screensaver (other than an Energy Star saver with an Energy</div><div></div><div>Star-complaint setup, or a backlight dimmer on an LCD) does not decrease your</div><div></div><div>monitor's power consumption. The US Energy Star programme will soon lead to the</div><div></div><div>demise of the screensaver as unused monitors power themselves down.If you use a Quadra, Centris, or LCIII, AND use an Energy Star-compliant monitor</div><div></div><div>(look for the star logo) off internal video on one of these machines, you no</div><div></div><div>longer need a screensaver. Apple's freely-available 'Monitor Energy Saver'</div><div></div><div>package enables the Energy Star features of your monitor with these machines.</div><div></div><div>Your monitor will power down in stages when the Mac is not in use, saving on</div><div></div><div>your electricity bills as well as saving your screen. 'Monitor Energy Saver'</div><div></div><div>(also known by its codename 'DarkStar') is available on
sumex-aim.stanford.edu</div><div></div><div>(info-mac/cfg/monitor-energy-saver.hqx), on AppleLink, and should be on</div><div></div><div>
ftp.apple.com shortly.If you have just bought a Color Classic or LC520, which follow Energy Star</div><div></div><div>recommendations, you should be using the Screen control panel supplied with the</div><div></div><div>System Software to automatically turn off the monitor circuitry when the Mac is</div><div></div><div>not in use - you DO NOT need a screensaver to save your screen, although you may</div><div></div><div>want to 'smooth' the intrusion of the monitor switching off by using a 'dimmer'</div><div></div><div>like Twilight. If you own a Mac with an LCD display you are unlikely to need a screensaver. The</div><div></div><div>only screensaver you would be interested in is one that dims the backlight after</div><div></div><div>a period of inactivity, to save power when running off the batteries - included</div><div></div><div>in various PowerBook-specific utility packages. LCDs can retain the colour they</div><div></div><div>are set to, whether black or white, in a 'memory effect' that takes time to</div><div></div><div>change, but does fade away. If you use a (probably unnecessary) screensaver, it</div><div></div><div>has been suggested that it should be one which flips all of the pixels</div><div></div><div>regularly, to prevent this memory effect. (This is unrelated to the ni-cad</div><div></div><div>battery 'memory effect'.) More information on both of these topics can be found</div><div></div><div>in the PowerBook FAQs of the Mac newsgroups. Read through</div><div></div><div>comp.sys.mac.portables.A/UX users may want to use something to cover the login screen. So far Moire has</div><div></div><div>been reported as the only screensaver doing this. DS and other startup</div><div></div><div>applications will never do this. Read through comp.unix.aux for more information</div><div></div><div>on this and other A/UX issues.Screensavers are primarily fun, decorative things to have around, and should not</div><div></div><div>be taken seriously. A screensaver is a useful for protecting your Mac from</div><div></div><div>prying eyes while you are away from it, and many screensavers include optional</div><div></div><div>password features for this. You may want a screensaver for its password</div><div></div><div>protection, rather than its 'screensaving' abilities.</div><div></div><div>--WHAT MAC SCREENSAVERS ARE AVAILABLE? (0.1)</div><div></div><div>Far too many. This FAQ concentrates on AD because it is the most popular, the</div><div></div><div>most well-known (being an advertised package), has the most support from other</div><div></div><div>programmers in the form of different screensaver 'modules', and because there</div><div></div><div>are other packages that can run AD modules. It's become a standard. AD is</div><div></div><div>commercial and costs money, although updates, bug fixes, programming information</div><div></div><div>and third-party shareware modules are freely available online.If you simply want to play the many shareware/freeware AD modules available from</div><div></div><div>ftp sites, get DarkSide 4.1 (see below). As AD (or Pyro!, or NowFun!) is</div><div></div><div>commercial, it and its commercial modules CANNOT (and SHOULD NOT) be obtained</div><div></div><div>from ftp sites. Updaters can be obtained by ftp, but they must update the</div><div></div><div>original package which you have bought. If you want to use AD (or Pyro!, or</div><div></div><div>NowFun!) or the modules supplied with it, you must buy AD (or Pyro!, or</div><div></div><div>NowFun!). If you are looking for a screensaver, it is well worth obtaining freeware and</div><div></div><div>shareware savers from ftp sites (
sumex-aim.stanford.edu in info-mac/gui,</div><div></div><div>
mac.archive.umich.edu in util/screensaver) and evaluating them before</div><div></div><div>considering commercial products.But first, read (0.0). You may not even *need* a screensaver with your</div><div></div><div>particular Mac setup.----Modular screensavers (0.1.1)</div><div></div><div>Modular screensavers, with a number of different effects, include:After Dark (AD) - commercial (brkly...
aol.com) The most popular. Has the most</div><div></div><div>modules available, and some third-party savers can run these modules. Includes</div><div></div><div>the screensaver, modules and programming information. More After Dark (MAD) is</div><div></div><div>an add-on package from BS that does not include the screensaver itself - just</div><div></div><div>add-on modules and an updater for the screensaver. Star Trek - the Screensaver</div><div></div><div>(ST), also from BS, includes the ST saver and modules, but not the programming</div><div></div><div>information included in AD. BS has just launched the Disney Collection, a</div><div></div><div>package similar to ST.Citadel 1.2 - commercial, by Datawatch. A security package reported as including</div><div></div><div>hard disk and partition locking, passwording, file encryption and destruction as</div><div></div><div>well as an AD-compatible screensaver. I haven't seen a copy of Citadel, and</div><div></div><div>cannot comment on something I haven't seen - tips welcomed. I know nothing</div><div></div><div>further.DarkSide of the Mac 4.1 (DS) - freeware, by Tom Dowdy, an Apple employee</div><div></div><div>(do...
apple.com). **DS 4.x also plays AD modules** (unlike DS 3.2 and earlier).</div><div></div><div>Like AD, DS includes a password feature and a Randomizer. DS runs as a startup</div><div></div><div>application under System 7. It only patches one trap when it needs to. As it's</div><div></div><div>an application you can quit it at any time if you need more memory, and restart</div><div></div><div>it later. (System 6 users want the older DS v2.5, the last version to run under</div><div></div><div>S6 - but they won't be able to play AD modules).</div><div></div><div>Some of the forty supplied DS-only modules (e.g. Circuit, LostInSpace,</div><div></div><div>VaseDance) are very polished and original and are well worth a look. Many others</div><div></div><div>(e.g. Searchlight, Worms) are similar to AD's and Pyro's, but with fewer cute</div><div></div><div>frills.</div><div></div><div>An up-to-date DS package can be ftp'ed from
ftp.apple.com (directory:</div><div></div><div>/dts/mac/hacks). A copy should also be on
sumex-aim.stanford.edu (directory:</div><div></div><div>info-mac/gui).</div><div></div><div>A number of people have posted, saying that they own AD and MAD, but that they</div><div></div><div>prefer to use DS to run their modules.</div><div></div><div>DS 4.1 uses less memory than AD does to play AD modules, and takes up less disk</div><div></div><div>space and less CPU time. It is claimed to run all AD modules, with the known</div><div></div><div>exceptions of the commercial BS ST modules ('for legal and technical reasons'</div><div></div><div>the ST modules require an AD 2.0x control panel. DarkSide can't see or play</div><div></div><div>these modules).</div><div></div><div>[If you use Okey-Dokey 1.0.1, turn off the countdown display, which crashes DS</div><div></div><div>4.0's password dialog.</div><div></div><div>If the MAD Confetti Factory module crashes, you are using DS 4.0. Get DS 4.1.</div><div></div><div>If DS still seems to crash, try giving it slightly more memory (your INITS may</div><div></div><div>be eating up a lot of program heap space) or trashing the DS Preferences file,</div><div></div><div>and see if matters improve.</div><div></div><div>If DS stays at the front on startup, check your Startup Items folder. DS should</div><div></div><div>be there only once.</div><div></div><div>If you keep your AD and DS modules together, note they both have 'Clock' and</div><div></div><div>'Puzzle' modules, and that MAD also has a 'Rain' module. Remove or rename one of</div><div></div><div>each.</div><div></div><div>To only randomize some DS modules, put them or their aliases together in a</div><div></div><div>folder, and open that folder with Open...</div><div></div><div>The docs are in MacWrite Pro format. Eventually, an XTND translator for this</div><div></div><div>should appear. One in the package would be nice...]</div><div></div><div> I'll attempt to detail further DS problems in this FAQ as I receive them.</div><div></div><div>If you don't already have a screensaver, want to write screensaver modules, or</div><div></div><div>are interested in using the wide range of free/shareware AD modules, this is THE</div><div></div><div>screensaver to get. The price is unbeatable.NowFun! - commercial. This 'fun' compilation package from Now Software is</div><div></div><div>reported as including FunScreenSavers, an AD-compatible screensaver with thirty</div><div></div><div>modules (many previously shareware), FunPictures (an updated DeskPict),</div><div></div><div>FunCursors, FunColors and FunSounds. I haven't seen a copy of NowFun!, and</div><div></div><div>cannot comment on something I haven't seen - tips welcomed. I know nothing</div><div></div><div>further.Pyro! 4.1 - commercial. This was the original 'fireworks' screensaver, and comes</div><div></div><div>with fifteen or so modules. The modules are similar in function to the DS and AD</div><div></div><div>modules. One or two third-party modules do exist, but nowhere near the volume AD</div><div></div><div>has - and, unlike the others listed here, Pyro! cannot play AD modules. DiskLock</div><div></div><div>1.2 is reported as being a commercial security program, with similar features to</div><div></div><div>Citadel, that also runs Pyro! modules. I haven't seen a copy of Pyro! 4.1 or of</div><div></div><div>DiskLock, and cannot comment on something I haven't seen - tips welcomed. I know</div><div></div><div>nothing further.Screensavor - Commercial, by MIFP Development (mbg3b2!mi...
uunet.uu.net or</div><div></div><div>pere...
sandy.ohsu.edu) . A 'specialist' picture displayer. Includes a startup</div><div></div><div>application (like DS) and an equivalent AD module. Sets of pictures (e.g.</div><div></div><div>landscapes, kittens) also available. Does fades, zooms, and other effects.</div><div></div><div>Shows GIFs and PICTs as well as its proprietary format - more flexible than the</div><div></div><div>AD Slide Show module.Twilight Zone - an entry for MacHack 1993 by Steve Falkenburg (no email address</div><div></div><div>known). Although it isn't a screensaver, this little application will run</div><div></div><div>AfterDark modules inside individual windows. The modules can be resized, moved,</div><div></div><div>run in the background, and more than one can be run at once. It won't run all of</div><div></div><div>the Berkeley Systems modules - it crashes on most - but, as an example, I had</div><div></div><div>Fractals, Mathos and Spinning Bow Tie running at the same time - faster than</div><div></div><div>they do when screensaving. It's the only way to run more than one module at</div><div></div><div>once. A copy can be ftp'ed from
mac.archive.umich.edu or its mirrors (directory:</div><div></div><div>util/screensaver/afterdark). It's unstable and buggy (it IS a hack!), and needs</div><div></div><div>work - anyone want to use the source code (included) or know where to email</div><div></div><div>feedback?----Standalone screensavers (0.1.2)</div><div></div><div>There are also a large number of small standalone screensavers to choose from,</div><div></div><div>and many are present in the gui directory of
sumex-aim.stanford.edu. Some aim to</div><div></div><div>be as simple, small and unobtrusive as possible (e.g. TinySaver 2.2,</div><div></div><div>FadetoBlack, BasicBlack). Popular choices include Eclipse 1.0 and Moire 4.01 (If</div><div></div><div>you are using Moire simply because it also includes a menu-bar clock, consider</div><div></div><div>getting the SuperClock! 4.0.4 control panel, which is far better, and another</div><div></div><div>screensaver. Moire is also available as an AD module - you can run it under DS</div><div></div><div>4). There are a number of screensavers for Macs that support use of the Brightness</div><div></div><div>control panel and dim an unused screen, e.g. Twilight. Twilight 7.1.4 onwards</div><div></div><div>also 'dims' the same way on all other Macs, by allowing you to install the</div><div></div><div>Brightness driver. The Brightness control panel can then be used on these Macs</div><div></div><div>as well.[If you want software brightness control, but don't want to install the system</div><div></div><div>software driver supplied for Twilight, a copy of the 7.0b1 Brightness control</div><div></div><div>panel, which works on all Macs, can be found on sumex in cp - someone has added</div><div></div><div>new icon and version resources.] If you do think you need a screensaver, look at what's freely available from ftp</div><div></div><div>sites first - particularly DS if you're running System 7 or better. You will</div><div></div><div>find something to suit you.</div><div></div><div>--HOW DO I WRITE SCREENSAVER MODULES? (0.2)</div><div></div><div>----Writing DarkSide modules (0.2.1)</div><div></div><div>If you don't own After Dark, but you have a neat idea for a screensaver and</div><div></div><div>don't fancy writing an entire standalone package, look at DS 4. All the</div><div></div><div>information and code you need to write DS modules is supplied within the</div><div></div><div>complete package. At present, I know of only two third-party DS modules -</div><div></div><div>there's definitely a market window here.If you are writing DS modules, bear in mind that older versions of DS have a</div><div></div><div>deliberately incompatible module format - DS 4 won't play 3.x modules, and</div><div></div><div>neither will play 2.5 modules. I suggest supporting 4.x (an easy upgrade for any</div><div></div><div>System 7/3.x users) and, if possible, 2.5, which is the last version System 6</div><div></div><div>users could use, although you'll have to dig around a bit to find a copy of </div>
