From the Past: Cities of the Future Slideshow
I have always loved those great Cities of the Future from the thirties even to the present; they always present some bucolic vision that is never quite achieved. Canon set up a vision at the CES show to showcase their high def cameras; Unpluggd said "Think Playmobil meets TV studio diorama."
it has a lot of features we talk about on TreeHugger: Green roofs, urban turbines, trees everywhere and sky walkways. It reminded me of some of the other visions of the future shown on TreeHugger; see a slideshow of them here.
