I don't _love_ calling myself an artist, but on the other hand I have been paid for an artwork before and so am technically a professional. Mostly I dabble and follow odd ideas as they come to me. Perhaps one day, when my energy isn't all going to my paycheck, this area will get bigger.
In no particular order...
Diamond-Square - Algorithmic terrain generation
Happy Trees - A forest of happified numbers
Viz - An in-browser emergent behavior visualization
