OK Danny I'll see how that one comes out. Hopfully I dont ruin it trying different things!
Your alien would look pretty cool with that material :O
Depending on the size, you would want to "Hollow him Out" for the print as they charge by "the Amount of material used" not the size of the piece. So I dont know if you can Shell him or just Boolean a sphere out of his belly. I think I just read here that MoI handles that "boolean a small sphere out of a larger one and having an enclosed hole inside of another closed surface action. This will be handy with this type of RPT.
Actually Burr, you've probably come up with the first 'Safety Ninja Star' for those times something or someone is annoying you :)
I could do the alien, but I'm afraid that the arms and fingers are a bit flimsy.
