Bored? Have some fun with the Browser Ball experiment. It's both ridiculous and pointless, yet fun and addicting.

It comes with a warning, however:

I make no claims as to the physical accuracy of Browser Ball. I have very, very little experience writing collision detection systems, and so, quite frequently, the ball will freak out for almost no discernable reason. All I can do is apologize profusely for my many, many shortcomings.

I keep trying to make the ball bounce all the way down a series of windows like a slinky down a flight of stairs. I get so excited when it almost makes it and then...OHHH! It stops!!!
