Thanks to Arjen Markus for his (mostly) weekly summary of Wiki action:
  Spring is in the air - well, according to the meteorologists on the
  northern hemisphere at least - and that brings us a nice little
  3D demo ...

  The light side of things
  - As said in the introduction: a nice little 3D demo at
    <http://wiki.tcl.tk/17771> - your chronicler (platonically)
    loves those solids.

  - Listening to music via your computer is no big deal nowadays ...
    even to the point where you don't know what you have anymore.
    Well, maybe these tools can help a bit - <http://wiki.tcl.tk/22616>

  - Spring, summer next: the ideas for projects in the Google Summer
    of Code keep being added - <http://wiki.tcl.tk/22182>

  The heavy side of things
  - Tcl's event loop is simply wonderful, but what if you want to
    insert your own event sources into it? Read this page for
    starters: <http://wiki.tcl.tk/17195>

  - As easy as Tcl is, there are those common mistakes that
    everybody seems to make. In fact, you can fill a number of
    Wiki pages with them - <http://wiki.tcl.tk/3798>

  - For a new feature like TclOO there always remain things that
    need to be done - <http://wiki.tcl.tk/22139>

  - Once you understand them, coroutines are big fun. Read all about
    them: <http://wiki.tcl.tk/21446> and <http://wiki.tcl.tk/22231>

Everything Tcl-related you want is probably one or two clicks away in these
pages:
    The "Welcome to comp.lang.tcl" message by Andreas Kupries
        http://www.purl.org/net/tcl-welcome
    comp.lang.tcl is a crucial resource for Tcl practitioners.
    An interesting perspective on its traffic appears at
        http://groups.google.com/group/comp.lang.tcl/about

    The Tcl Developer Site is Tcl's "home base".
        http://www.tcl.tk

    Larry Virden maintains a comp.lang.tcl FAQ launcher.
        http://www.purl.org/NET/Tcl-FAQ/

    The Tcl Developer Xchange is a highly organized resource center
    of documents and software with provisions for individuals to
    maintain references to their own software:
        http://www.tcl.tk/resource/
    The TDX sponsor, ActiveState, also keeps info to convince your
    boss Tcl is a good thing
        http://www.tcl.tk/scripting/

    The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
    of documentation, examples, tutorials and pontifications on all things
    Tcl.
        http://wiki.tcl.tk/0
    For the ideal overview of the topics about Tcl most likely to
    interest a newcomer, see "Arts and Crafts ..."
        http://wiki.tcl.tk/969
    There's also a high-quality Wikibook on Tcl:
        http://en.wikibooks.org/wiki/Programming:Tcl

    ActiveState maintains binaries distribution and development tools
        http://www.activestate.com/Tcl
    along with a Cookbook of Tcl recipes
        http://aspn.activestate.com/ASPN/Cookbook/Tcl

    "La Gazette du Técleux" is an important monthly publication.
        http://wfr.tcl.tk/1159

    deli.cio.us presents an intriguing approach to reference commentary.
    It already aggregates quite a bit of Tcl intelligence.
        http://del.icio.us/tag/tcl

    Cameron Laird tracks several Tcl/Tk references of interest (but
    needs to validate many of the links).
        http://phaseit.net/claird/comp.lang.tcl/

    Years ago, Cetus Links maintained a Tcl/Tk page with verified links
        http://www.cetus-links.org/oo_tcl_tk.html

    "Yahoo! Groups" archives comp.lang.tcl.announce posts--even
    though clta itself is dormant.
        http://groups.yahoo.com/group/tcl_announce/

We're working on more useful archives of past installments.  Dave
Williams generously is building up
    http://www.bacomatic.org/~dw/comp/tclurl/index.htm
and of course Google gives us
  http://groups.google.com/groups?oi=djq&as_q=+Tcl-URL&as_ugroup=comp.l...

Suggestions/corrections for next week's posting are always welcome.
