I have to admit that I’m a bit of a fan when it comes to Easter Eggs. Easter Eggs, if you didn’t know, are little surprises programmers sometimes live inside their programs for users to fine. uTorrent, a BitTorrent file trading client, has a pair of them. From the Help -> About drop down menu selection, press the ‘T’ key on your keyboard for a decent game of Tetris.
Also if you click on the uTorrent logo within the About popup, you should get some music that you may recognize.
