[Edu-sig] VPython/Tk visualization of residue classes

[Fred Yankowski]

I've been experimenting with ways to provide animated visualizations
of simple mathematical concepts, and I'm fairly pleased with my latest
effort which displays "residue classes" for different modulus values.
The VPython/Tk program is available temporarily at
<http://ontosys.com/src/residue2.py>.  Note the Tk controller window
that starts up along with the VPython display window.

This program is motivated by the material in Chapter 2 of Conway and
Guy's "The Book of Numbers" book.  I think someone on this list
recommended the book; it is a wonderful exposition of various patterns
of numbers.
