Underwater cups -- a puzzle piece
A puzzle piece... Anyone want to guess what these are?
Stereo, cross eye. Frame width about 8.9 mm, shot as two stacks through about 1/4" of water.

Pierre, thanks for taking a shot.
These structures did form in contact with a liquid emulsion, but I'm unclear whether the solid forms shown here are emulsions also. Definitely no glass was involved.
The cup-like structures were originally covered by an opaque liquid. I first observed them when the liquid was drained. Then I rinsed them a couple of times with clear water and left them covered with a thin layer of water to eliminate distracting reflections during photography.
Harold, definitely not algae, but I agree that the appearance would suggest that.

Thanks for dropping in, folks.
No bread or sponges involved here, except in the environment surrounding the subject. Not much lime scale either but that's definitely working in the right direction.
I'll add that the cups formed quickly, a few minutes at most.
Here is another view of the same structures, this time with a wider field and looking straight down.
The cups were a "found" subject that I just happened to notice. I was intrigued by the 3D structure (thanks, Wim!) so I took some time to photograph them.
This morning I specifically tried to reproduce the cups using a simplified setup. The attempt was promising, but not entirely successful:
I hope this helps!
