Best Spinning Top

Play with this interactive top with your kids, at board meetings, or on the go! Just put your device on a flat surface and tap the top to get it spinning. Tap multiple times to make the top spin faster. You can drag and flick the top around with your finger while it is spinning, but it will slow down if it touches the sides. Tilt the device and watch the top slide around.

Richard Feynman won a Nobel Prize studying the relationship between a top's spin speed and its wobble. Where will playing with this top take you? If nothing else, use it to tell if you are dreaming or not.*

*May not be metaphysically possible to tell if you are dreaming.

Fix a bug that prevents the app from running on iPhone 3gs, iPhone 4, and iPod Touch.

Namely, the listed devices will not load a texture that isn't sized a power of 2. I changed a texture to be sized as a power of 2, (and made the program fail a bit more gracefully if texture load fails)
