Another suggestion that I have is for a furniture making artist by the name of Peter St John. He lives in the east bay with his studio in the back yard. Between making his own sea worthy fishing boat and an RV to camp in the desert, Peter has kept his life interesting by making all kinds of personal furniture, mostly of wood and often found wood.
One of his projects has been to design rocking chairs that are customized so that they are perfectly balanced for a given person but will tip out someone with a different body size, weight, height, etc. For the body that they are designed for, it is complete comfort.
