At first I thought this was just another colourful abstract microscope image of the mineral Marston Jasper. But zoom in and look more closely at the fleshy lump in the middle of a picture – first I saw an eye, and then realised that part of a doll’s face was watching me from within the stone. I may never sleep again. This specimen comes from Central Oregon.
(Formed by stacking two or more images at different focal lengths to compensate for limitations in the microscope optics.)
