While an interesting demo of 3D with head tracking it can lock up your iPad if you hit the sleep button while its open. When trying to wake-up the iPad the app is displayed again and the iPad is frozen. It will not power down or anything else except display the frozen application. Hold down the power/sleep and home button until you get an apple. Take your fingers off the buttons and press the power/standby button again. Now press the home button. Your iPad should come back up. I had to try this a couple of times to get it right.
THIS APPLICATION NEEDS TO BE REMOVED!
