The kinetic sculpture displays the mosaics using visual cryptography. In visual cryptography, a message is encrypted by dividing the information of the message into two `shadow' images, each which look completely random independently. The message is decrypted and revealed when the shadow images are combined/overlayed in a precise orientation. In the kinetic sculpture of a history of the domino problem, the shadow images are printed on photomasks, which are essentially high-resolution transparencies: quartz wafers with a chrome coating etched at a pixel size ranging from nano- to micrometers. A high-precision, motorized multiaxis aligns the finely printed shadow images to reveal the mosaics (along with 3 other images of poetic texts inspired by the history of the Domino Problem).
