This is both absolutely fascinating and totally senseless: the World as a Blog. Basicaloly it is a world map in flash format with new blog entries popping up as balloons at the geographic locations of the blogs the new entries happen to appear in. I love it!
When you are there you can also log in using your geocoordinated URL so that others can see you watching them. Useless but funny.
Via hebig.org, more technical background there and at the site itself.
