Mark Hansen is one of the nicest and most intelligent people you’ll ever meet. He was one of the speakers at the symposium at last Fall’s Visualizar workshop in Madrid, and Medialab Prado has now put the video of Mark’s talk (and others) online. Check it out:
Mark has a Ph.D. in Statistics and along with his UCLA courses like Statistical Computing and Advanced Regression, has taught one called Database Aesthetics, which he describes a bit in his talk. You might also be familiar with his piece Listening Post, which he created with Ben Rubin.
