Salt evaporation ponds
Salt evaporation ponds
Very intriguing picture and backstory! Salt evaporation ponds.
Originally shared by Sergey BrinFloating over the San Francisco Bay, it is hard to miss the amazing colors of the salt evaporation ponds at the southern tip. Depending on the salinity level of a particular pond, the color can vary from green to orange to red based on the ecosystem that flourishes at that concentration.
As you can probably guess, I took this shot from an airship.
Jun 2023 update: The original picture link is lost to the death of Google+, but I found several images on the internet. Here are a few of what seems to be the same place, but with different evaporation levels = colours. Pretty much every colour in the rainbow, and several outside it, can be found in these salt ponds.

Ted Adelson's famous checker-shadow illusion
Ted Adelson's famous checker-shadow illusion
Optical illusion, with proof and explanations. See video on this page to understand that an Amazing Optical Illusion Shows That Our Eyes Are Horrible Light Meters
Originally shared by Sara SuThanks to +Norman Ramsey for sharing this 3D recreation of Ted Adelson's famous checker-shadow illusion. Due to the beautiful complexities of the human visual system, two checkerboard tiles of identical luminance have different apparent luminance (or brightness). In a previous life, I kept a collection of such illusions on the door of my office to amuse and hypnotize colleagues. Some favorites are here:

QR codes don't need to be a boring mash of black and white pixels looking like a screenshot of a TV screen without a signal. (Do you remember those? There used to be a time without 24-hour programming!)

Cinemagraph
Cinemagraph
A cinemagraph is a static image, in which the artist creates some motion, and converts it into a looping animation.
Check out the first one I ever came across. My comment then:
Sheesh, this is so enchanting, I've already forgotten who shared this with me.
