Well, it's a start. I think clay will work a lot better than play-dough has.

Just so you know, this is half a bug torso. No, it's not just a blue turd. This does look a lot like what I hastily made, though it's lumpy. I'm going to need to score calibration into stuff (another reason clay will work a lot better).

Interestingly, you can actually see my finger indentations in it. There's somehting kinda cool about that somehow.
I suppose it will help if was better at modeling play-dough. I'm better with clay.
