Rolling On

Well, we’ve certainly had some fun in this chapter with physics and the amazing iOS accelerometer and gyro. We created a great April Fools’ prank, and you got to see the basics of using the accelerometer as a control device. The possibilities for applications using the accelerometer and gyro are nearly as endless as the universe. So now that you have the basics down, go create something cool and surprise us!

When you feel up to it, we’re going to get into using another bit of iOS hardware: the built-in camera.
