SpeedCoder
Type real source code in 15 languages and race other coders live
You type real source code taken from open source projects, with a finger guide that shows which finger to use for each key. You can also paste or upload your own code. In race mode you type against other players live, and a ghost race lets you try to beat your own score on the same snippet.
