Build Your Home In TunnelSpace!

NASA churned out a lot of concept art in the 1970s while the agency was exploring ways to build colonies in space. NASA concept artists created trippy pieces like the Cynlidrical Colony above, and Torodial and Bernal Sphere colonies as well. We'd like to imagine that you could low-grav the whole thing, and just leap from one side of the colony to the other. Of course, it's not quite clear what would happen if you ran into one of those giant window sections. Hopefully they're made out of some synthetic diamond material to keep accidents from happening.

Don Davis, who painted this piece, has worked at NASA for years, and he's responsible for concept art on everything ranging from these space colonies, to the Voyager program. He's worked at the Ames Research Center, which is the mecca for speculative science fiction/faction at NASA, located in California. When he wasn't working on art like this, he was also collaborating with Carl Sagan, and contributed to Cosmos, for which he won an Emmy. You can check out more of Don's retro-futurist paintings at his website, where he also has an impressive number of Burning Man trip reports as well.
