Noel Hidalgo is trying something different with Luck of Seven.

on the luck of seven is an open-source, around the world project by noel hidalgo (aka noneck). for seven months, he will visit the seven continents, sail the seven seas, and visit the seven ancient wonders of the world. Using a wiki, noneck will harness the collective knowledge of the globe, and report weekly on seven topics of freedom. Before he leaves, he is fundraising US$11.11 from 700 global residents.

An interesting project; track the success though the blog and wiki, join the Flickr Group and go and donate.
