The motion-sensors in Apple's latest laptops are there to counter a very real threat - they stop the hard disk in an instant to try and protect your data just in case your laptop takes a nasty fall. Here's a nifty program that lets users take advantage of this novel feature by playing at countering imaginary threats Star Wars style. It senses speed for the lightsaber movement sounds and acceleration for different levels of striking sounds.

This beta obviously doesn't work with older Mac laptops, of course. For those lucky enough to own one of the newer ones, enjoy swinging them around like crazy!
