Spinor

With a grateful nod to G. t'Hooft, and also as described in the Feynman lectures, this is a demonstration of an object that one needs to rotate through 4\pi (two full rotations) to get back to its original state rather than 2\pi (one full rotation). Such objects are called spinors, and play a role in classifying states in quantum mechanics.
