Everything is by me ---------------------------------UPDATE!!!--------------------------------- It now has a thickness bar, so you can change the thickness of the pen to your preferences! :D Press the Left Arrow Key to run through the full sequence. It is long, but very cool. Press the Right Arrow Key for a shorter sequence. Press the Up Arrow Key to pick random numbers. To see each shape really fast just turn on turbo mode and press the left arrow key I will not be able to reply to all of the comments, but I will do my best with the ones that mean something.
