The nice dude in the campsite next to ours has started a company to send postcards to space, and you can do it for only $25!

He talks about the experience of X Prize Cup here. Mike, Kevin, and I get a mention :-)

NSS Space Settlement Calendar Art Contest
From the NSS website:
"The National Space Society (NSS) is looking for artists to create visions of a spacefaring future — a future of space settlement, be it on the Moon, on Mars, on asteroids, or orbiting independently in space. To bring attention to our goal of creating a spacefaring future, NSS is sponsoring a contest for such artwork to be used in a calendar promoting a future of humans living and working in space. The best of the submitted artwork will be selected for inclusion in the 2008 NSS Space Settlement Calendar. "
