[pygame] "Node Based Visual Programming Language"

[Bill Coderre <bcbc@xxxxxxx>]

I want to write a game where there's some "critters" living on a plain, wandering around, fighting with each other, eating grass, etc.

I want to program the brains of the critters with a graphical, hook-stuff-up type programming language, like, say, Quartz Composer on the Mac. (here's a handy picture: http://en.wikipedia.org/wiki/File:QuartzComposerSnowLeopard.png )

Anybody done anything like this using Python/PyGame?

Thanks for leads.
