Bottles are exposed behind the bartender. They line up on two long shelves and become partially hidden by sandblasted sliding doors. The translucent quality of those doors allow us to perceive the shape of the bottles in the back. But little by little one would notice slight changes in the overall shape of the shadows of the bottles, and soon you will realize that those shadows are twisting and expressing their own playful life.
It’s probably time to quit drinking, right? By the time you point out to your neighbourg the strange phenomenon, the shadows will most likely have returned to their expected positioning in front of each bottle. But you, you are hopefully still trying to find a good explanation.
