The things people come up with these days...
If you've been on the Net for a while, you've probably seen buttons or tags for Digg, which is a community-based news management and relay website. The idea is that news articles are submitted by users, and everyone else on the site votes on how interesting, relevant, or helpful the articles are. Articles deemed popular through this method rise to the top (theoretically) while unhelpful articles sink to the bottom and are lost (again, theoretically).
Somebody developed a Tetris-like game seeded from Digg's RSS feed. For every article submitted, a game piece enters play. It moves pretty fast, and is very responsive for a Flash game, so check it out when you've got a chance.
