Surprisingly interesting and really well presented --- the animations are inspired.<p>Personally, I love big, ugly skyscrapers (I've been trying to get myself onto a tour of the Gherkin for Open Doors Day for years). I do agree with the decision to limit them to one particular district, though. London's got a lot of fantastic buildings which don't want to be overwhelmed, and besides, skyscrapers look best from a distance.<p>(I didn't know that views of St. Pauls are protected by law! And I'm embarrassed to say that I never even knew about the Great Fire of London memorial...)
