The wooden mirror has 830 pieces of wood each about 40 mm square arranged into an octagon of 35 x 29 . Each piece of wood is connected to a
servo motor that can tilt it about 30º up and down. The whole piece is lit from above with a few spot lights, in a way that when the pieces are tilted
upwards they become brighter, and when they tilt downwards they become darker. The servo motors can position each piece in 255 positions theoretically yielding
255 gray levels per piece.
Love it. Want one.
