DESCRIPTION:A "rubber band" constrained to remain on a manifold evolves by
  trying to shorten its length\, eventually settling on a closed geodesic\,
  or collapsing entirely. It is natural to try to consider a noisy version 
 of such a model where each segment of the band gets pulled in random direc
 tions. Trying to build such a model turns out to be surprisingly difficult
  and generates a number of nice insights\, as well as some beautiful algeb
 raic and analytical objects. We will survey some of the main results obtai
 ned on the way to this construction.
