C. RESOURCES Among the wonderful modules you should definitely stop at Kirby's pages.
These are mostly linked from: http://www.inetarena.com/~pdx4d/ocn/cp4e.html I've gotten a lot of mileage out of the Python + Povray synergy, the latter being a powerful, no cost ray-tracer. Povray runs off ascii text files (.pov) which you can have Python write. I mostly can (or bottle) polyhedra in Python, using a primitive vector class. Here are some of my fancier graphics, developed with Python's assistance: http://www.inetarena.com/~pdx4d/ocn/concavedodeca.html Crytography is another topic I take up. I've got both letter substitution cipher modeled on Enigma (sort of), and an intro to RSA (patent expired on that algorithm, kids can use freely). All this stuff is non-GUI (I use Python's IDLE for development, itself a GUI). There may be nothing suitable as is, but there might be something that sparks an imagination or two, plus example source code. Kirby
