Theodore Gray, who is responsible for those stunning Periodic Table of Elements works I've blogged about before, points us to this beautiful 3D Hilbert fractal in neon, which is about four inches tall.
Theodore explains, "It was a gift from Richard Crandall, a long-time Mathematica user and Apple fellow who also has a business, Perfectly Scientific, which sells algorithms, lab equipment, and scientific art, including this lovely object." More about the artwork here, including some video and QTVR panoramas.
