WOW!
After reading this post I did a google search for smack book and have just spent the last 45 minutes or so watching awesome videos on youtube of motion sensing apps for the Macbooks. I thought it was only a simple sensor that noticed large motions like dropping, I didn't realize these laptops have a full on gyroscope practically built right into them!
I am excrutiatingly amazed! More details please. Where can I get these apps? I also searched for that but couldn't find much.
