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,
