For those who do not know what Tauntauns are, here is some Star Wars 101. Tauntauns are beasts of burden and transport on the planet Hoth in the world of Star Wars. They featured in Empire Strikes Back as the mode of transport for Luke Skywalker and Han Solo.
Scott made this amazing costume from scratch. Using designs made in Solidworks, he started to outline the Tauntaun. The head mold was detailed using clay, then a mold was made , then it was cast, and on and on. The horns were made in almost the same manner. Tedious process some say, I say it was passion for what he was doing.
