So I have given three talks in ten days or so, one at the CanSAS meeting at NIST,  one at Drexel University and one at MIT last night. Jean-Claude Bradley was kind enough to help me record the talk at Drexel as a screencast and you can see this in various formats here. He has also made some comments on the talk on the UsefulChem Blog and Scientific Blogging site. The talks at Drexel and MIT were interesting.
