Something fun for your Saturday morning. Check out this website. It allows you to pretend you're Jackson Pollack.
Here's how the site looks when you first load it:
Move your mouse over the white space and you'll notice splotches and dribbles and paint everywhere.
Click your mouse and the paint color will change.
How cool is that?!
By the way--the disclaimer/text in the lower right corner only appears when you hit "Shift+Ctrl" and try to take a screen shot.
