Actually, I want to see most of the visions in the database come true - many of them are just balls-out awesome, and it's a crime they haven't been built. I'm very glad I found the
visions/fantasies/stale proposals portion of the diagram database, because it's a treasure trove: These buildings are way more interesting than most of the ones that end up being built. I wish I could post the renderings here, but I don't feel like asking ten separate people for copyright permission.
Anyway, what vision/fantasy/inactive proposal /cancelled projects do you most wish to see built?
