Information Architects Japan, a design agency based in Tokyo, has been producing maps of the Web based on the Tokyo underground, and is looking for comments on the version 3 beta. There is still time to add sites.
It's quite a bit different, and I notice The Guardian has moved across town. The beta has the usually-annoying Snap previews, which in many cases show RSS feeds instead of home pages -- but it's hard to be too critical as iA's own site is also a victim.
If you've not had the pleasure, see Web Trend tube map, looks like Tokyo, which was in this very spot last July 25.
Thee will be versions you can print out, and iA is promising a nicely printed A0 size for your wall, if you have $50 going spare.
