  The Iteratively Smoothing Unigrid algorithm (ISU), a new multigrid method for
computing propagators in Lattice Gauge Theory, is explained. The main idea is
to compute good (i.e.\ smooth) interpolation operators in an iterative way.
This method shows {\em no critical slowing down} for the 2-dimensional Laplace
equation in an SU(2) gauge field. First results for the Dirac-operator are also
shown.
