Abstract:     A negative bust illusion is formed of a surface (representing a negative of an object) that presents a concave side to viewers to generate an illusion that the object always gazes at viewers as they move within an enlarged field of view. The negative bust is analogous to a mold of the object, with its depth flattened to impart a wider effective range the illusion. The rigid shell has a cavity that defines the bust and is formed of a thin, translucent styrene material such that rear projection is readily imparted to the convex side for imparting animation to the gaze effect.

First Claim:
Show all 22 claims
We claim:     1. An apparatus for providing the illusion that a bust of a face portion of a head continues to gaze upon a viewer who moves past the head in a path extending through an angle originating at the bust, said apparatus comprising:
  • a rigid shell framed by a horizontal and vertical framing plane, said rigid shell defining a cavity extending into a depth direction perpendicular to said plane away from the viewer, said cavity shaped to define a negative, three dimensional contour of the face portion of the head;
  • wherein said shell is composed of a thin, at least partially translucent material that is a rear projection surface, such that images projected upon a convex side of said cavity are visible to the viewer, who views a concave side facing the predetermined path; and,
  • a projection device that projects images upon said convex side.
