Origami Brain

How big a square of paper, for a brain-sized brain? (The folds of the brain increase surface area, which is where the action is--this would be a fantastic visual aid for a biology or psychology class! Mr. Chan ought to put together a video of its creation, and sell it to the textbook weasels.)

Very impressive. I am in the process of conceptualizing a brain made out of paper for my 3D design class and I came across your creation. I am curious to know if you have any pointers for me. What is the scale of your brain? How big was the piece of paper you used? Any help would be great. Thanks
