Space Balloon?

If aerial photography from a kite isn't quite high enough for you - how about a home-built balloon rig (digital camera, GPS, custom micro-controller, radio, alarm, helium balloon, etc.) that managed to climb to over 50,000 feet, snapping photos the whole way! Just a couple of guys looking for something cool to do!

Here are the photos, and here is the story - it was quite an adventure.
