Science Friday has a great video featuring mathematician and reluctant sculptor John Edmark. His fascination with spirals, and math-based sculptures, has made him somewhat of a legend. Utilizing the Golden Angle and the Golden Ratio, Edmark creates amazing pieces that seem to defy physics with the way they move, open, and spiral infinitely. But the designs are based on math, and nature has been building like this for millions of years. His work is available for purchase through 3D printing company Shapeways. Definitely worth a watch.
