Insert a speed value. This is how far the game object will move before executing another movement. Next, enter an iteration amount. The more iterations the more movements the game object executes. Iterations scale exponentially so high numbers result in long loading times but bigger fractals. To keep it all on the screen I recommend having lower speed values for higher iterations.
This is a fractal drawer. A fractal is an enclosed shape with an infinite perimeter. This isn't quite a fractal unless you set the iterations to infinity... But it is still there in concept.
