Crystal rock pattern under a microscope
This is a recording of a thin slice of rock under a special type of microscope that has a polarizing filter above and beneath the specimen. Without the specimen, it is totally black because of the orientation of the polarizing filters, but because the different crystals in the rock shift the light around some light makes it through the second polarizing filter. This view is only of light distorted by the crystals.
