Chris Fassnacht (UC Davis) came into town and we discussed various things lensing. He showed us some very beautiful Keck AO images of strong gravitational lenses. He also discussed with us the generalization of blind deconvolution that includes a lens model in the middle of the generative model. This is a great idea, and no-one really has the whole package. He and his collaborators have great evidence for massive substructure in lensing galaxies.
