I think JacksonPollock.org is my favorite website to visit when I'm feeling a little uninspired. It's a flash program created by Miltos Manetas, a London-based painter who believes "Our websites are the Art of our days", that lets you create digital Jackson Pollack look alikes just by moving your mouse. Click once to change colors and press any key to "sign" your painting. Kids will probably really get a kick out of this, and parents will love the easy clean-up (which entails hitting the space bar). My JacksonPollock.org masterpieces might not be "Autumn Rhythm: No. 30" by any means, but yours might be, check it out here.
