M.C. Escher, Another World / Andere Wereld (1947)
This is almost my favorite image by Escher. But I’d like a frEscher perspective in it: I think the bird should be looking in the other direction, out into the impossibly overlapping universes, not into the cupola and at the viewer.

I hadn’t seen this one before – it’s really cool.
I liked the hooks holding the horns to the ceiling. A bad modern artist would have them floating in space: but here there’s a little nod that physical laws still apply, even if they’re different to our physical laws. (Plus it adds another ring/spiral/circle motif.)
It’s surprisingly un-well-known. I don’t know whether the horns would mean more to Dutch-speakers, but I assume they’re there partly as a mathematical form and partly as a joke, because it’s all taking place in the lunar vacuum or some equivalent. The bird’s wings would be part of the joke too.
