Indeed, it is a picture of the moon reflected on water. It was taken on Saturday evening and the water was a bit choppy. Looking at the patterns it formed it reminded me of flocks of birds chasing each other. Of course, it also reminded me of worms digging tunnels. or even more fun: a gas of strings.
No, it’s not a Rorschach test nor a simile. It is indeed the reflection of the moon on choppy water. Because of the optical conditions of the surface of the water, it is hard to recognize it as such. The lack of context (other visual cues) is what might make it seem like such a test.
