Stuffed Beagle - You Might Live in a Mudflood City If You See Pavement, Prism, & Vault Floor Lights

This is a video by Stuffed Beagle Productions about a subject I didn’t know about. When I lived in Oklahoma City between 2012 and 2016, I became aware of sidewalk lights in the downtown area that I was told was because of stimulus money the city received after the 1995 bombing of the federal building. Regardless, when I look at the origins of the sidewalk lighting, said to have its start in London in the late 1880s, the folllowing things come up: --Some cities removed these lighting systems, and some preserved it --Found in city-centers --I am seeing Flower-of-Life, geometric patterns --Question Glass vs. Crystal Origin --How big of a stretch is there between Luxfer prisms, and Lucifer? Just wondering.
