Way back in 1990, Amalgamated Dynamics, Inc. produced a wonderful animatronic puppet based on designs supplied by H.R.Giger. When I’ve had the time, I’ve been chiselling away at this homage. Reference would seem to be light on the ground, and there are a few different sources, but there was enough to arrive at my own facsimile. I don't know if the exposed armature was part of the design or not, but I think the resulting "exposed bone" effect is pretty cool.
