Liz and I built little go carts this year.  Liz had a mobile mushroom with Horton the elephant riding along.  It doesn't actually make sense, but we liked to try to convince people it did.  Nikolai had the Trojan Rabbit.  He was unsuccessful at infiltrating any castles while on the playa, which is sad but appropriate.  Unfortunately, we have only one picture on-playa that includes the Rabbit's ears.  We attribute this to him having some Easter Bunny genes in him.

The bottom row shows a few steps in the process from concept to Rabbit.

The Rabbit also ran out of gas at one point, and the upper right image shows Liz towing Nikolai's dumb ass back to camp.
