relativity.jpgI'm still kind of stunned by this, but check out Andrew Lipson and Daniel Shui's recreation of the famous M. C. Escher drawing, Relativity. They've got some pretty fantastic photos of how they constructed the thing here. Oh, and because I can't resist dropping facts, I read this on Wikipedia about the Lego® company: "The Lego group is the largest tire manufacturer in the world, producing over 300 million minature tires each year."
