Whoops, I just overwrote the triangle. :( I'll fix that later. Flash turbo recommended. I first made this in BYOB, a Scratch modification, a while ago. BYOB has recursion built-in, which made it easy. I decided to take on the challenge of making something that required recursion--a fractal, such as this one--in Scratch, which doesn't support recursion. And it worked! This takes up a lot more memory than the Sierpinski Triangle does, by the way. Just letting you know. :)
