TuxPaint -- too much fun

I don't care how old you are or how badly you draw -- TuxPaint is a heck of a lot of fun. OK so it's purported to be a paint program for kids. Just download it when no-one's watching. It's available for Linux, Mac, and Windows.

One of the best parts about it is the zany sounds that accompany each action. They're hilarious. Be sure to download the optional Stamps. The stamps and the Magic (effects) are cool. I quite like the Grass tool.

Here's one of my creations that came out of nowhere after I'd noodled around with it for a few minutes. (Try the Smudge and Negative tools!).
