Basic, but complicated. Space - to paste in the save code (sorry mobile). Click - to change the shape of the already in-use shape. Yup, that's it. after 2 hours of torturing my brain with ongoing brainstorming, thinking, and testing... i present to you- this... project... which was worth it... I hope. Don't look through the code if you don't like math. There's plenty.
Code: me surprisingly Give credit to use. I hope this works...
