This looks like a glass bead craft you could buy at some souvenir shop in, say, New Mexico. But this is real corn, and it's not the result of patient injections of dye, either. It grows this way.
They call it glass gem corn, for obvious reasons, and it's specially bred to have such a variegated kernel-by-kernel color scheme. You'd almost feel bad for eating such a work of art, but you'll feel better knowing that the next day it'll be Mardi Gras in your toilet.
There Is No Glass in the World Strong Enough ...
If there was just a pee hole in the floor, this would be perfect.
That's not a Photoshop, and it's not a realistic painting on the floor meant to freak out houseguests. That's a real shaft that you could really fall down into and die if that pane of glass ever failed while you were sleepily taking a piss in the middle of the night.
This bathroom is in an upscale penthouse apartment that was built in a refurbished building in Mexico. The joker who designed the place thought it'd be funny to put the bathroom atop an old elevator shaft, and to make the floor out of glass, and then the guy actually freaking did it, with what had to have been an absurd amount of effort and expense (imagine the process of installing that floor). If you're not scared of the height, wait until a flock of bats decides to come flooding up out of the darkness while you're taking a dump.
