Me too. I love it. It could be so many things---A weird sort of eclipse? the eye of Cyclops? the last thing you see before going under anaesthesia? a compromised pearl? a black hole in space?
Yep, as everyone says it could be something different for everyone who looked at it.
For me the first thought was an xray of a Polo mint(other mints are available) being checked in quality control for minute cracks.
Hope that don't sound too wierd....Great image.
