[fkmnwkty] Polarization of material

Striking is the appearance of some glass when viewed through a polarizing filter, e.g., sunglasses: patterns of rainbows on what is normally perfectly clear.  Seems possibly to be caused by the glass under stress and strain.

Can the pattern of polarization be controlled?  Hidden artwork.  A way of encoding information into the physical structure of a material.
