Thanks to Arjen Markus for his (mostly) weekly summary of Wiki action:
The Easter weekend has passed, so we are well into spring/autumn in the
northern/southern hemisphere. Time for a summary again.
The fascination of weather
- Create your own animations of the weather patterns that interest
you: Tcl makes it rather easy - <http://wiki.tcl.tk/19663>
- But not only observed weather can be visualised. Here is a tool
to deal with information on the predicted weather:
<http:/wiki.tcl.tk/23170>
Mapping stuff
- Geographic maps are at least as fascinating as weather. Here
is some information on what Tcl can mean in that area:
<http://wiki.tcl.tk/736>
- Interpret "mapping" generously, and you get a system for
mapping handwritten formulas to computer-readable ones:
<http://wiki.tcl.tk/23169>
- And a survey into the realm of Tcl use is a kind of mapping
too. Have a look at the figures and the accompanying analysis:
<http://wiki.tcl.tk/23153>
Potpourri
- Writing your own window manager may not be given to everyone,
but it is a more than a whim. See for yourself - and read the
article this page refers to - <http://wiki.tcl.tk/13972>
- Should weather fascinate you, you may also be interested in
spying on the stars in the nightly sky. Well, that can be
done in a most Tclish way too: <http://wiki.tcl.tk/17564>
- Just a proof of concept, for now at least: an Easter weekend
well spent by your Wiki chronicler: <http://wiki.tcl.tk/23148>
- Perhaps more immediately useful, annotations on the canvas:
<http://wiki.tcl.tk/23156>
- And to conclude: yet another example of the use of coroutines.
This time to see how they hold in a simulation environment:

Everything Tcl-related you want is probably one or two clicks away in these
