If you like Macs and StarWars, you’ll love MacSaber. It’s a little app that turns your MacBook into a lightsaber and something that’s sure to make Mac fanboys look even cooler than they already are…
Using your MacÃƒ¢Ã¢â€š¬Ã¢â€ž¢s sudden motion sensor, this software turns your computer into a Jedi weapon almost worthy of taking on the real thing by making authentic lightsaber sound effects. It senses speed for the lightsaber movement sounds and acceleration for different levels of striking sounds.
r2d2 would be proud.
