It's simple. 5 balls changing costumes every 0.5 second. Each ball has a different method of doing so, and as you can see the "variables" part is slower. Click "see inside" to see the code.
100% by me. 64 blocks. Sometimes you think things are similar, especially the four that looked exactly the same, however they are completely different. Each method has its own strengths and weaknesses, used in different situations.
