The talk at Quinnipiac went well -- it was a nice drive down and I got there with enough time to sit in the quiet and get some work done before my talk. I finished off a working version of the first 
"unknown" gene expression model. Eventually, I plan to add a pop-up menu that will let students select among 8 unknown problems. The goal of each problem will be to knock genes out in order to deduce what the regulatory relationships among the genes. I think it's cool. I don't what anyone else will think.
