The central image on this page is of the interior of a Bernal sphere – or something very much like it. The outside is spun to create gravity and the internal axis provides stability. I liked this because there are not a lot of depictions of this particular solution in science fiction comics and it was great to see it show up here. Subsequent pages have the ground at various angles to emphasize the effect, but because the background is not explained, it isn’t obvious what is going on.
