Did you realize that your new iPhone or iPod touch includes an invention of the industrial revolution? The gyroscope, invented by Johann Bohnenberger in 1817, is a device used to measure orientation in a 3D environment. The gyroscope has evolved to the point where a miniaturized version can now be included in a mobile phone. While you may have already had some fun with your last iPhone or iPod's built-in accelerometer, you're about to enjoy a whole new realm of apps and games thanks to the gyroscope.

Gyro Draw allows you to sketch via motion. Isolate the gyroscope or the accelerometer and have a little fun learning about how these components track motion in your new iPhone.
