Secret knocks

Now that's a cool application of technology. Seen on Slashdot: “Knock” Some Sense Into Your Linux Laptop describes how to set up Lenovo Thinkpads to respond to a series of knocks on the computer case. I'm sure someone will turn that into a totally small-scale authentication system (“What's the secret knock?”) or maybe a totally hacked up drumming system… ;)
