The floor, walls, and ceiling are flat, black, and reflective - like LCD screens. In the center of the room, two yoga mats - matte black, slightly spongy, otherwise nondescript - face one another, and in between them is a floor lamp with a lime green LED bulb glowing softly, and a tray table with a single clear, cylindrical glass on it, filled to the halfway point with liquid that gives off its own faint cyan light.
