Watch! Bsically you get five random spirals, because the spiral script randomises it. Then the 5 sprites clone themselves, and draw a spiral. Next, a variable called 'Ready' will add 1 to it. Once its value is five, it makes another clone and starts drawing, clearing all the previous designs and clones. It just repeats, and every time the 'Ready' variable equals five, then the backdrop will switch to a random colour. Enjoy!
