I ordered one of these for my dad for Christmas one year, and as we live in the Bay Area, I opted to just pick it up from Cliff Stoll’s house. Guy was one of the nicest people I’ve ever met—introduced me to his family and gave me a tour of his workshop, including the robo-car he uses to retrieve the bottles from his crawl space. My dad got a kick out of the bottle but has probably since forgotten about it, so I think I got more out of the gift than he did!
