Over the weekend, MacSaber was released. On a MacBook or newer PowerBook with motion sensors enabled, you can effectively turn your laptop into a lightsaber sound machine. I recently got a new iBook, but unfortunately the software isn't compatible with the motion sensor installed in my laptop. I could move the window around to make the sound effects, but that isn't nearly as cool as being able to swing the laptop around and scare the pants out of people afraid of the evil Emperor.
Luckily for the rest of the world, this guy has put the MacSaber program to excellent use by recreating one of the great moments in internet history.
