Probably the silliest app I've ever built. Designed and coded over 24 hours during the 2009 Yahoo Open Hack Day in NY. Was a lot of fun. Built in AIR with only the native Flash 10 3D engine (no papervision or similar).
Each "peapoe" is linked to a YQL query that it monitors. Whenever it's content changes, the peapoe jumps. The more unread items it collects, the taller it gets.
Told you it was silly.
