basically, yes. There is also the option to just sculpt a ball of putty and let it cure, even fingerprints are allowed, we don't expect nothing too fancy, just some ball . painting it up is the next step and kinda way more important. there is tons of possibilities on what to paint on a sphere.
Really? Counts my idea out then.- It is not allowed to resculpt the ball, i mean for example do a mouth or eyes in it or building a tank around it, like "Uh! In this tank is my ball!" Fail!".
