Spherical Harmonics for Cosmology and Mathematical Art 
One likely model for the shape of the universe is the PoincarĂ© dodecahedral space, which is a quotient of the 3sphere by the action of the icosahedral group. To help cosmologists, Jeff Weeks adopted a method originally proposed by Klein to find all the spherical harmonics invariant under the icosahedral and other polyhedral groups. In trying to connect the method to polyhedrallyinvariant functions on the 2sphere, we discovered an interesting connection to selfmappings of the 2sphere, opening the door to a new technique for mathematical art. (Joint work with Jeff Weeks.)
