Aquatic Illusion by Moonset (1989)
This is what doing astronomy does to your brain. I got the idea for the
three-pronged-thingy-which-is-two-pronged from the mind of M. C. Escher. One of my
favourite early pictures, this is. I think I was getting the hang of oil pastels by
this stage. Interference patterns on water look absolutely nothing like that. But it
looks subtly weird this way.
