I had a huge entry written up on buying an mp3 player... and then I got totally thwacked by this:http://files.deviantart.com/f/2004/188/8/7/gridgame.swf
It's... addictive. My current high score is 2558. It's so satisfying once it really gets going, the thwoopy noises...
I'm going back to it now.
EDIT: Whoops, got so entranced I forgot to mention that I unabashedly stole this from theraevyn
