Here are the body sculptures that Nathan created. The Brain is the yellow sculpture with the cerebrum and cerubellum (I hope I spelled that right), a spongy bone marrow piece with veins and arteries around it, and the heart, lungs, and diaphram scuplture. The amazing thing is that Nathan doesn't look at pictures while he is creating these things. He has seen pictures, and he then remembers it in his head to build this stuff. I love to watch him create, as he knows exactly what he is doing, and what pieces of Legos he is looking for. He doesn't do this in a random way. I think he might be an architect or engineer some day.
