J. A. Sethian  
A paper and movie of a curvature collapse. A famous theorem in differential geometry, proved less than ten years ago, says that any simple closed curve moving under its curvature collapses nicely to a circle and then disappears. That is, no matter how wildly twisting a curve is, as long as it is simple, it will "relax" to a circle and then disappear.
