In process photos for 111 P3. Sorry about the craft, sketch models :)
The first one is fairly simple and just demonstrates the hinge action of the elbow.
The second one has the upright end cube rotating around the back face of the lower cube. I liked that when it is upright you could almost expect it to hinge but it rotates.
The third one has a couple of concepts within it that I am going to explore further. The two cubes spin relative to each other on the short side, something that I am thinking about incorporating into a different design. The other is the hinge action and the rotation on that same face.
I would like to do something with both a hinge action and a rotational element…let us see.
