I think this is the direction I am going to go with my entry. Ascension's "Island of Misfit Toys" map gave me the idea. It'll be inspired by the "Santa vs. The Snowman" computer animated short that came out years back. I'm thinking about using some villain from the classic old "Rankin-Bass" stop motion animated toons too. I'll be going with a very "hoth battle" feel with legions of snowmen and elves with jet-packs and candy-cane rifles.

I'll post a preliminary sketch of the map as soon as I can, but just wanted to put the idea out there.
