The observer effect is a phenomena wherein the very act of observation modifies the behavior of a system under scrutiny
Multiple gears rotate to create a polygon indicatedby the black thread. All gears have a different number of teeth, which makes them fall out of sync with each rotation. This behavior allows for generation of unique polygons every time the gears move. When approached at an arms-length distance, the sculpture responds by changing it's configuration to create a new pattern. Hence, the observer is able to actively create new sculptures, merely by focusing their attention towards the work of art.
