Juergen of Random Good Stuff posted a few neat photos of an elevator that looks like it was taken straight out of The Jetsons. Here's the Globen Sky View in Stockholm, Sweden:
The Sky view globe elevators run outside the Ericsson Globe which is currently the largest hemispherical building in the world and took two and a half years to build. Shaped like a large white ball, it has a diameter of 110 metres (361 feet) and an inner height of 85 metres (279 feet). The volume of the building is 605,000 cubic metres (21,188,800 cubic feet). It has seating capacity for 16,000 spectators for shows and concerts, and 13,850 for ice hockey. (wiki)
