Thanks for the suggestions.  I keep waffling on whether to make the snow more
realistic or not.  The scene is a bunch of ornaments, so the melting snowman is
meant to be a bit of humor, but I had also considered making him a real snowman

suggestions as I can see other uses for having a good model for snow.
