Line Rider: Drawing was never this fun.

A little Flash-based game premiered on Deviantart about a month ago, that involved nothing more than a white background, a simple line drawing tool, and a midget with a red scarf. That game is Line Rider, and it might possibly be the most addictive game I have ever seen, save for the big red button game. It's a physics based environment, where you draw a "virtual ski slope" for the midget with the sled, and you can draw lines, loops, slopes to end with the perfect landing. Pssh, who am I kidding? You're trying to hurt him as much possible. It's really pretty scary how much fun you'll have just knocking the crap out of this guy. So with no further ado, I bring you Line Rider.

Oh, and if you're not the creative type, watching these user-made videos on Google Video might be almost as entertaining.
