This project was created at a CS4HS workshop sponsored by Google at MIT. If a LEGO WeDo tilt sensor is hooked up to the computer, the bird on the screen can be contolled by the tilt sensor (or ideally contolled by a LEGO bird with a tilt sensor attached to it). The bird flies left, right, up and down. There are 4 background screens to create a scrolling background effect. A cactus sprite appears on the 3rd background, and the layering effect is used to get the bird flying behind the cactus.
