Dig Your Way to China
Or, in my case, dig your way to the Indian Ocean. In case you've always wondered, "If you a dig a very deep hole, where will you end up?" there is now a Google Maps based web application to help you figure it out. The page is written by a Brazilian student, so the English is a bit sloppy, but the concept is kinda cool. To dig your way to China you would have to start in Argentina or Chile.
