Move around your mouse to paint with CRAZY FACE. Press space to change costumes. Press clear to clear what you did. If you press space enough, then you will get a blank costume. this helps you leave spaces and gaps. Go to the blank costume and press the flag if you want it to be a different size. Press space if you start out with the blank costume
Thanks to @natalie for scripts, I just took the rotate part out to make the lines less jagged.
