We calculate the homology (under d, as well as dually under delta) of the complex of harmonic forms on smooth manifolds with boundary, without imposing tangential or normal boundary conditions. The resulting Hodge theory has an exotic summand, isomorphic to a shifted copy of usual homology. (This is joint work with Dennis DeTurck, Herman Gluck and Edward Miller.)
