Daniel’s Circles Mirror is an amazing combination of mechanical and digital technologies. By using a radial gradient from black to white, each of the 900 overlapping discs rotates to create the illusion of shades of grey.
Rozin create custom software to convert the digital images captured by a video camera into data which could be used by the motors which rotate the circles.
