I've corrected a mistake in the download package to accompany Python 2.0.
If you already installed that zip file, you need to copy the
C:\Python20\Idle folder into C:\Python20\Tools to invoke the enhanced
version of Idle.

At vpython.org is a new version for Windows which fixes a problem with
losing "press" and "click" mouse events. If you have already installed
VPython for Python 2.2 on Windows, you need only download the DLL file and
unzip it into the Python directory.

I made a mistake in the deployment of the color stereo versions
yesterday, now corrected (Win/Linux/Unix/OSX). And by the way, public
thanks to Rob Salgado for bringing up the possibility of color stereo
with red-cyan or yellow-blue glasses.
In the current implementation fully saturated object colors are
displayed with 50% saturation, which ensures that both eyes have
something to see. With the 50-cent red-cyan paper glasses I have, the
cyan filter almost perfectly excludes all red, but the red filter allows
quite a bit of green through, making ghosts in the view seen by the left
eye. These ghost images are more or less noticeable/annoying/distracting
depending on the details of how extreme the stereo is, the background,
etc. Even with shutter glasses there are some ghosts, though typically
less noticeable. However, shutter glasses plus a special graphics card
are a lot more expensive, and there is flicker unless you can drive the
monitor at a very high repetition rate.
It would seem worthwhile to see whether it would be possible to find a
red filter that passes plenty of red light yet excludes almost all green
(and blue). I don't know whether this is feasible, given the overlap in
sensitivity of the red and green receptors in the eye.

Since green is the brightest of the primaries,
I wonder why nobody uses green-magenta.
