How about a yellow brick road spiraling up the tiers with memorable scenes on the face of the cakes. Uh, like some munchkins, the poppy field, emerald city skyline, hmmm...that's all I can think of off hand. It's been a while since I've seen it....OOOooo with witches legs sticking out of the very bottom of the cake! Oh! And don't forget the flying monkeys (on wires?) flying over the cake.
Hahaha....I totally go overboard. I can't help it. It's fun!
