You can click on "Show" to see the full program.

The method drawFrame is called 20 times; frame is a different value each time, the graphics object is new each time. Draws a yellow rectangle at coordinates (50,8*frame-20) which is (50,-20), (50,-12), (50,-2), (50,6) ... (50,172) So the yellow box appears at the top of the image and moves down a little with each frame.

Shooting Star

In this example both the x and the y coordinates change at each frame and so the star moves diagonally.
