Thomas Dolby and ETHEL
At one point I was entranced by the beam of light prominently reflected off of the giant closeups of Dolby's pate. Wasn't able to capture that but I was glad to get a decent shot of one of their fine performances.
I didn't get a picture of the bagpiper Dolby chose for the opening of the first session, but I had dinner with him. He was really cool -- young guy whose day job is working as a security guard, happens to be a guitarist and piper. He's really into philosophy and is a big TED fan. One of the most interesting people I met at TED.
