Standord torus
Artwork by Don Davis (1975)I have written a review of Elysium for the Lancet, examining the claim that the film depicts some kind of "Obamacare in space", and comparing it to what must surely be a principal influence: Don Davis' extraordinary paintings of the proposed Stanford torus space station.

(I have previously posted about this on my Tumblr blog, as well.)
