My dad(Being an avid mac user)downloaded a program for the mac side of his laptop motion sensor,when you activate it you hear the sound of a lightsaber starting up,if you leave it alone will hum like the blade but if you move it then it makes the exact sound of a saber moving,and move it hard enough it will make the sound of lightsabers clashing.It sounds like your holding an actual saber in your hands! :lol:So needless to say my dad and I have been having fun weaving his laptop back and forth.(though I'm sure the laptop wouldn't agree)
