This 18-min film just blazes by, but it really shows how cities can (and should) evolve. It also shows how collaborative projects (like Life Plus 2 Meters) can work so well.
Bottom Line: I give it FIVE stars for vision, style and inspiration based on what's actually happening. (We are going to Japan in July, and I'm excited to explore this "elegant civilization".)
Also highly recommended is this "School of Life" video on How to Make an Attractive City, which looks at what worked as an inspiration of what to do.
