Any Processing users here?

I was just curious to see if anyone here knows about/uses the Processing programming environment. It has interfaces for JavaScript, Python, and Ruby, and it may interest the tinkerers among you. I noticed the software mostly because the guy in the demo video on their home site did a (somewhat manic) coding challenge video on youtube about the Recaman sequence. AppleScript’s own script editor could possibly stand to take some cues from theirs.
