It's interesting how one generation's vision of utopia often becomes the dystopia of the following generation. In his time, Le Corbusier was heralded as the genius of modern architecture. Today, his buildings seem vaguely dystopian (to me, at least) and remind me of the recent 2012 Dredd movie.

Fuller probably envisioned the shape of his buildings as futuristic and naturalistic, but to me, they look like nuclear power plants. Icons (as in a simplified, recognizable image) end up playing an unexpected role.

From the countries I've visited, I'd say Berlin (especially Prenzlauerberg) and Tokyo had the most pleasant version of urban design. With Berlin, most apartments have balconies, streets are wide enough to let shops expand onto the sidewalks, and public transit works extremely well. Tokyo mixes commerce with residential in a way that American cities get completely wrong.

There is also a city in Poland, Łódź, which also has a geometrically appealing layout: it's essentially a single long street with two concentrations at either end. The city itself is still recovering from the 90s and is fairly run-down outside of the center, but the conceptual simplicity has an appeal that's hard to describe.
