My Starcraft Hydralisk Zerg costume made for You Got Game convention last 2006. I only remember seeing two videos of it in action, one shot during the catwalk, and this. This was shot in our garage, where a friend of mine wore it because he wanted to borrow it for a Halloween party. Added some sound effects.
The costume was retired, its fate documented in my old Livejounral entry back in April 19, 2008: http://teeth-for-eyes.livejournal.com/2008/04/19/
