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!".
