UPDATE: Version 1.1 is now available.
Now that you’ve spent entirely too much money on your fancy sudden motion sensor equipped Mac laptop, I predict you’ll soon be swinging it around like a loon.
Introducing MacSaber. Using your Mac’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.
This beta is not yet compatible with the motion sensors in older Mac laptops, but I understand you can move the window arond to get the idea.
Update: Thanks go to Sak from Lot23 for the fancy icon!
