A somewhat crappy "reproduction" of a linoleum cut by Escher,
using only two ambient spheres, a reflective plane with normals
and a POV-Tree mesh.

I haven't seen the Escher, but this reminds me of the first incantation of
Oliphant Down's song of Pierrot...
Baby don't wait for the moon
She is caught in a tangle of boughs
And mellow and musical June
Is saying good-night to the cows.

Looks like a cover for a Dean Koontz novel...

I think it reproduces Escher's work very closely. Very well done!

This is very interesting because it shows just how good Escher's sense of
geometric realism was. If you look at the distorted tree shapes reflected
from the rippled areas and compare to Escher's drawings, the match is
incredible. Sometimes I think the man was a walking raytracer - the only
raytracer ever to output directly to woodcut & lithograph!
Nice image. I'm working on an Escher myself at the moment, I'll post some
results tonight.

Escher erroneously drew the moon's reflection as distinctly oval.

I think that image has been squashed. Looks fine here:
