I finally had a chance to tour Heathrow’s Terminal 5.  And while I didn’t get a chance to dine at Wagamama or shop at Tiffany & Co., I did get a chance to see some of the great artwork that was commissioned for the building.  One of my favorites: CLOUD,  a digital sculpture by Troika made of (now) old-fashioned flip-dots, the technology once commonly used on schedule boards in airports and train stations.
