How it works
This project is a remix of the VGA Playground Checkers template. An additional counter (called offset) was introduced that doesn't count linearly but starts fast and then slows down which results in a bouncing motion. Furthermore the number of layers were reduced and the direction and speed of the movement were adjusted. Making the rearmost layer faster than the first one gives sometimes the illusion that the front layer moves in the other direction.
How to test
Similar to the checkers template on the VGA Playground the first five buttons can be used to adjust the colors.
