Move your mouse around, and the snake will follow it. If you go faster, the space between one color and the next will be bigger then if you go slowly. Also, if you want to get the snake to stop press space and afterward if you want to continue press the A key. And if you want to clear the screen press the C key.
I don't know, I randomly came up with it and made it in about 30 minutes. You can share your combinations in the comments.
