I squealed over this photo - http://www.flickr.com/photos/phonakins/4726479801/in/set-72157624203111858/ quite simply because I'd seen it.. well.. sort of. Actually we never did get to see much of Frankfurt in person, however we did see it at Legoland...

Look at the detail! Look how accurate it is! (Look at the cross-hatching of that middle building - there's a bit of asymmetry on the second-top floor, which is actually like that in real life!!)
Very squee :)
