I hadn't had PIL installed, and it wasn't downloading went I first went to
get it, so I hadn't been able to look at this before.
I can now, and so did now.
I hadn't had PIL because I've never have done much outside of vector
graphics.
I am used to working at the graphics object level, not the pixel level.
I think your demo ties the two concepts together in a fun way.
Thanks,
Art
