[Visualpython-users] "Shoot the Monkey" Demo, new shapes

I've written a little demo of the classic physics demonstration "Shoot the 
Monkey."  It is available from this page:

http://unix.cap.american.edu/~jwk/class/monkeyshoot.html

Bruce, thanks for your reply about implementing new shapes.  I can't 
understand the difficulty in implementing opacity for shapes.  Wouldn't you 
just change the color value under the one you're plotting, instead of 
replacing it?

Thanks also to Shuan for his instructions about hacking your own shapes into 
the C++ code.  I wish I had time to work on developing the VPython library 
(it's fun stuff), but at present I'm overbooked with a full teaching load, 
as well as a job search for after the semester.

In case anyone else out there has the time.  Other ideas for shapes to 
implement are the Platonic solids.  Other ideas you might grab from the COG 
radiation transport package, which implements a pretty complete set of 
space-bounding surfaces.  The manual is available here:

Look under the "SURFACES Data Block" section about a fifth of the way down 
the page.

JK
