(Blue Puddle is in Testing.
Look for a Beta version in Fall 2006.
(Feel free to check it out. It may be a little buggy.))
Blue Puddle is an interactive online mapping tool developed by an interdisciplinary team of students at the University of Michigan. The Blue Puddle software takes advantage of the Internet’s distributed authorship capabilities to create maps that draw on users’ collective memory and subjective experience of a city. These maps foster the emergence of stories about the city that are more rich than any single author could create.
