MegaMan Effect
Dan Dickinson's blog pointed out the MegaMan Effect. This little gem from the ADHOC/MacHack conference is a little Mac OS X app that runs in the backround, and anytime you launch an application you get a full MegaMan styled intro to that application complete with stars and music. Sure it's just a novelty, but on slower macs that have a delay before launching applications anyways, you may as well have a song and dance first right?
