Dr. David Huffman (of the Huffman Codes, for all you C.S. geeks) pursued a fascinating sideline in computational origami. His daughter showed his amazing curved paper structures to the New York Times. The folded forms look impossible to create in the typically straight-edge world of traditional origami. Huffman, who died in 1999, published only one paper on his folding work, though he pursued it from the 1970s and studied the underlying mathematical models. OrigamiUSA is holding a convention in New York City this weekend.
