First think of any letter or any abstract picture that you can think of. Then the tiny little box in the corner will show you your previous drawing but in slightly lower quality. Next step is to try to copy that tiny picture and press space or click outside the drawing box if you're done (AND DON'T DRAW NOTHING). That's it, a few iterations and it's almost done. Make your own alphabets! I'LL GIVE IT CLOUD ONCE I'VE FIGURED OUT HOW TO MAKE LISTS THAT ARE CLOUD.
