Migrated from the account 'IsMuHo' Imagine your hand is touching a cold wall. Through a thermal camera, the fingerprint/smear shows up looking hot, because your hand heated the wall, to the shape of whatever symbol you were making. Here I've tried my best to re-create that through Scratch in the form of Sprite cloning, but in order to have a smooth motion, the clone limit needs to essentially not exist, thus for the choppy motion.
