The Model that I used in the making of my short Killer SNoBALL FROM Mars. made from clay, eyeliner, and Snow-Tex for texture You can find the short on youtube if you look, but be forwarned, the movie is INTENTIONALLY hilariously bad (special effects include snow made out of diaper-filling and a beard made out of what appears to be a dead animals fur and Elmer's Glue, etc.) so this is probably the best EFFECT you're gonna get.

Also, I'm aware that it looks like it's sitting in "yellow snow", but it's supposed to be radiation XD.
