The problem of constructing supersymmetric lattice theories is an old one dating back to the earliest days of lattice gauge theory and has resisted solution until quite recently. I will show how new ideas borrowed from topological field theory have afforded a solution to this problem and describe one of the most interesting applications; the construction of a supersymmetric lattice regularization of N=4 super Yang-Mills theory. Large scale Monte Carlo simulations of this theory are now possible and have the potential to yield new insights into the structure of this theory at strong coupling and away from the planar limit.
