Spheres

These shots were taken for fun to show the amusing sort of things one can do with ultra-transparent (inclusion free) crystal balls.
It concludes this week's installment of images and, unless there is a barrage of requests pleading more, sphere photography.
The designs seen through the crystal are scrims (screens for cutting/diffusing light). One has a square weave and the other a hexagonal weave. The magnification is strong enough that these resemble the interference figures seen in petrography. A glass rod with a ball on the end is used as an analyzer in conjunction with a polariscope to test gemstones...same sort of thing.
At any rate, this is end of spheres...
