On the start screen, click "Random" to generate a random pattern. Click "Code", and it will ask you for a 49 digit number consisting only of 1s, 2s, and 3s. Any more or less digits than 49 will stop the project from running.
I only made it go up 6 layers, because it sort of glitched out at 7. Bug: you also can't just copy & paste the code, you have to remove the spaces. :(
