A box made of a wooden board (80 x 80 x 80 cm), lit up with lightboxes, with an aperture at the bottom; two-way mirrors, frosted glass, LED lamps, and snow-white stones (Greek pebbles).
A room filled with stones. The stones lie on several layers of fabric and sponges, which act like a loudspeaker. Each step in the empty rook is extremely loud.
