See the following update posted by "tuskentrooper" on the official 501st Legion website:

"As we countdown to Celebration V, the 501st TK Project is picking up the pace with three more customized Stormtrooper helmets. Two of the replica helmets donated by eFx Collectibles are Steampunk-themed buckets by artists Brian Rood and Kevin Graham. Both feature a Victorian boiler-plate metal and rivet look, with Graham's copper-plated helmet having the bonus feature of fully-functional built-in speakers and a 5-port USB hub! Amy Provonost's entry is something like the bizarre lovechild of TK-421 and Wicket the Ewok complete with leather, feather, fur and beads. All of the helmets in the TK Project will be up for auction at Celebration V in August with proceeds going to Make-A-Wish. Click here to see them all!"
