Information Architects has created a 2008 Web Trend Map,. They have taken almost 300 of the most influential and successful websites and pinned them down to the greater Tokyo-area train map. As they said, “By popular demand, we enlarged the poster size from A3 to A0. We guarantee it will make a great addition to your home or office.” You can get a paper version suitable for framing or a clickable online version.
It reminds me of the global trends map for 2007 produced by Ross Dawson last December. He based it on the famous London tube map by Harry Beck.
