Just watch while four sprites are "stamping" around. One is the leader, the other three are followers. It's their job to do the opposite of one of the others to make the patterns symmetrical.
credits to @PinkyPepper for the project I remixed credits also to @Paddle2See for the original project all I did was change all the costumes, no changing of scripts lol some of the patterns looks like whipped cream to me! please tell me what the finished patterns look like to you
