Pong in the favicon
A while ago I stumbled upon DEFENDER of the favicon, a game based on Defender which uses some nifty javascript hacks to display the game in the browser favicon. It's pretty impressive, and now I just realized that the same guy has put the classic game of Pong in the favicon. It might not be very practical, but being a developer myself I really find it to be in the higher regions of awesomenimity scale. Play it here.
