Space.com has more on John Carmack's ISDC 2007 talk. Some of the most interesting points (just read the whole article if these sound interesting):
- Pixel has flown dozens of times since the 2006 Lunar Lander Challenge.
- There seems to be some commercial and government interest in using Pixel to house instruments.
- There are thoughts of using the platform for "Space Diving", or very high altitude skydiving.
