This is just an experiment for a shape for final structure. Above is the original shape following the rules of:
.start with a square
.add 2 triangles
.take away a circle
.add a square
.take away a semi circle
Above is the same shape at the top but cut on the fold so that when it fits a person you can make it symmetrical.
Above is how I see the miniature paper version scaled up to fit the human body. I love the shape it creates, ultra 80's "power shoulders". But it does look like a robot or something out of the Transformers film.
