David found a few weeks ago, and I joined, and I love it! It's a place for artists of pretty much every medium to share their visions of space exploration, extraterrestrial worlds, future, etc.
Well, Boris, the SAN founder, was approached to start a ! It's completely visionary and completely in the beginning stages of pre-production, but we're on track to make it something wonderful.
