It becomes a mark
Its yin-yang is where everyone starts.
The paint on this wall changes all the time, as each visitor adds to it. This mark keeps the yin-yang from one summer: draw over it, or match it with your camera.

The reveal
Same wall. Everyone's story.
Everyone who stands here makes their own take on the same mark. Add yours and the reveal plays them all, one becoming the next.
Example takes. Generated examples. The reveal stays locked until you add yours.

About 200 meters around the wall.
Its mark unlocks within about 200 meters (650 feet) of the wall. Unlocking it isn't the same as photographing the wall: you take it by matching your camera to it, or by drawing over it. Anywhere else, it stays locked.
