Ok ; we'll I'm painting a vivid picture of all the parts you would need; but so far I'm only getting smoke patterns... I know you will need an electro magnetic motors ; I know you will need bearings made of copper ; that will be able to conduct electric energy; while also sending a feed back to your computer; I don't know if you can miniaturize the motors I've seen online; I also don't fully know all the gears that will be needed ... But if you have ideas please share with me. $UM.GØD
