<p>A sculpture (10) provided with a concavity (16) carrying a relief negative impression (18) of a formation representing a true object, the formation having selected features of proportion: ratio selectively of height: width, of length: width and of depth: width different (1.3:1) compared to the corresponding proportion: ratio of the true object as 1:1. Observation of the sculpture (10) under illumination by a moving observer evokes to the observer, a three-dimensional virtual illusion of movement where the sculpture appears to move in the direction of movement of the observer. A process of forming the sculpture (10) includes the steps of forming sculpted copy of the formation; forming a first alginate/plaster mold carrying a negative relief impression of the formation; forming a second alginate/plaster mold using the first mold, the second mold carrying a positive relief impression of the negative relief impression of the first mold, thereafter casting using the second mold thereby forming the sculpture.</p> |
