Yeah, to reproduce that, I'd probably have to print out the schematic fairly big, trace it onto a two or three foot square of paper, and resign myself to messing up horribly at least a dozen times before making any progress at all. I know I could manage the actual folding if I could figure out what I was meant to be doing; I'm good with my hands and have made origami in the past, but that doesn't mean I can make sense of the diagram. That guy is pretty much amazing.
