Google, as the most accurate search engine (by the way, is there any other search engines at all? I wasn't aware of any..) has recently been more and more in the center of attention. So many programmers use their new public API and play with it these days to develop their ideas into practical applications.
Three quick examples:
elgoog: an exquisite geeky Google mirror! Use the link and search the net, it's a cool joke! kcul doog!
Touchgraph GoogleBrowser version 1.0: shows related links to a particular web site in a visualized way (useful for link: addicts).
Google Setvista: A similar project to visualize Google Sets. To learn more about Google sets, please read our previously published article.
