Check out these crazy limited edition custom Reeboks by artist/programmer/author/MIT professor John Maeda. They are called Timetanium and are designed to represent Maeda's theory on how to simplify time. The interior lining of the shoe shows the handwritten code used to create the graphic on the exterior of the shoe. The graphics starts out very complex and colorful at the heel and gets simpler with more linear lines and minimal color at the toe. If you want a pair of these it is already too late. They only produced 100 which sold out within the first day or so. (Found through Cool Hunting).
