This time, a special architectural post. These photos are of a hidden weed farm in Tennessee. The guy who invested all his time and effort into this hidden grotto of treasure deserves a medal. Obviously, I wouldn't be writing about this secret place if it hadn't been busted. The police apaprently found a sophisticated operation which grew as much as 100 pounds of marijuana every eight weeks. How was he busted?
The thick metal door to the secret passageway was held in place by a hydraulic motor. If someone didn't want you to enter, you would probably need a small bomb to get in.

The explanation can be found in the way our Visual System perceives the world. The visual system is not very good at being a physical light meter, but that is not its purpose. The important task is to break the image information down into meaningful components, and thereby perceive the nature of the objects in view. Logically, you expect the tiles to be differing colours cos of the pattern in the pic.
