Knock-based commands for your Linux laptop

The new Macbook’s aren’t the only laptops you can knock, slap and bump to perform commands – “For the first time, you can hit your computer and get a meaningful response!

Double tap to lock the screen, and knock in your secret code to unlock. Tap the display lid once to move your mp3 player to the next track. The possibilities are endless.” [via] – Link.
