Michal gabriel, Jan Ryb‡Ž, Lucie Svobodov‡ PROJECT - SCULPTURE In one of the arcades in Prague - ideally the Lucerna arcade - we would set up a projection screen. Made of resistant material the screen would be hanging from steel wires. A projector, computer and camera n.2 would be installed in a protected place. The projected picture would be a sculpture which would move in accordance with the spectatorÕs distance to it. At the same time the spectatorÕs figure would be reflected on its surface. The computer would be transmitting the reflection onto the sculpture from camera n.1 next to the latter. This camera would be filming the spectator approaching the screen. All of this would be happening in real time. The sculpture itself is a simple geometrical form - a sphere. This sphere would unfold and reform following the principle sketched out below and demonstrated by the photo of the already existing sculpture. In the arcade people would be passing by the screen and could watch the moving sculpture from both sides while it would be reacting to them. They would be reflected on its surface. The sculpture would be quietly floating in the air, indestructible, with precision not attainable in reality. We have already tested the project three times and with every new realization it has improved in quality. We have no doubts that we can realize the project.
