CHEZ ARC-EN-CIEL Sydney Cash, 151 Reservoir Road, Marlboro, NY 12542, U.SA Received 28 February 1990. Acceptedfor publication by RogerF. Malina. Chez. Arc-en-Ciel (Fig. 1) is an optically kinetic glass construction. It was created from plate glass that has been silk-screen printed with a computergenerated linear graphic pattern. The planes of glass were cut, ground and then glued together with a silicon adhesive on all edges. The viewer sees the moire patterns that are created by the visual interaction between the graphic pattern on the front plane and the graphic pattern on the back plane of the sculpture . As the viewer moves in front of the piece, the moire patterns also move. Each section has a unique motion generated by the angle formed by the planes and the angle formed by the lines on the planes. The front surface of this sculpture is a simple plane in the shape of a house. The narrow central peaked section of the back is parallel to the front plane, and the moire line patterns that move up or down stay parallel . In the side sections of the back, the ellipsoidal moire lines move both horizontally and vertically. The movement of each side section is in opposition to the other. The roof sections have a more complex moire line movement due to their more complex angles. exposed card. What is written is a function of the 'program'-information stored in the form of three irregularly cut cams. The mechanism is activated by pushing the cart forward. Rotation of the wheel axle is translated through a wire 'worm' to the platter that holds the three Plexiglas cams. As the cams rotate, lever arms following their irFig . 1.

This motion is delivered to the hand through push-pull cables in flexible shafts. Each lever arm/cam pair is responsible for one of the possible X, Yand Z directions. Xand Y allow the pen to move anywhere on the card. Z allows it to leave the surface to cross t's, dot i's, and return to the beginning of the word. Since the program FASTER! Arthur M.
