Movement trial on the Gantz hard suit. The costume worked like a giant puppet with a lever system for the arms/hands/fingers.
The suit was mostly 20mm foam with a structure of cane underneath.
The hands are Fosshape of varying thicknesses and the back of the hands is Wonderflex for strength because when the wearer gets tired the hands touch the ground a lot.
The suit is about 120 cm wide at the shoulders and about 230 cm High, it just barely fit through a doorway sideways.
I was lucky enough to win the Avcon costume competition in 2013
