TURBO MODE! Wait for it to repeat the script 30,000 times and hopefully it will have generated a cloud! Choose a mode then press the green flag again. Mode 1 is a blockier cloud but will generate faster. Mode 2 is a higher quality cloud but will take longer to take shape.
The dot creates 5 clones, they start in random places, then turn in a random direction, move 1-5 steps, then stamp. Then it repeats 30,000 times.
