Made with Processing?

so, i’m chatting with a client this evening and he asks me if i know anything about Processing. my reply, of course, was “processing what?”

then he sends me these links:

http://www.wefeelfine.org/
http://www.processing.org/exhibition/

this stuff’s been made using a language called Processing. i haven’t read into it yet, but the end result seems to be pretty similar to the dynamia Flash is capable of.

anyone heard of it, worked with it, mastered it?
