For a homemade suit and head with opening and closing mandibles it's pretty darn cool. The pics speak for themselves and he obviously put a lot of time into the tutorial. I can only imagine the hours he put into making that...
It is a well planed out tutorial. The fact that the majority of what he used, is homemade. I wonder how much the suit he made costs compared to a Macguyver suit [I think I spelled his name wrong--sorry].
I too ran across a nice site. It boasted some interesting graphics, which I’m more than sure went with an equally interesting and detailed topic. But it was in Spanish! I wish I could have it translated.
