Abstract
The present invention provides a sculpture bound within the volume of a polyhedron that when, rotated about an axis of rotation and positioned in the path of a directed light source, cast shadows of a predetermined and desired form onto a surface.
Claims20
A sculpture bound within a volume of a polyhedron having a first plurality of pairs of registered faces comprising:
- a first plurality of plates connected together in parallel spaced relationship with a plurality of spacers, the plurality of spacers formed in a process other than a process that formed the first plurality of plates, to form a first number of layers with gaps between adjacent plates, the first plurality of plates having surfaces extending transverse to a first pair of registered faces of the first plurality of pairs of registered faces and arranged to cast a first shadow of a predetermined shape when the sculpture is positioned at a first angle of rotation about an axis and in a light path of a source of light directed at an oblique angle to the surfaces;
- a second plurality of plates connected together in parallel spaced relationship with a plurality of spacers, the plurality of spacers formed in a process other than a process that formed the second plurality of plates, to form a second number of layers with gaps between adjacent plates, the second plurality of plates having surfaces extending transverse to a second pair of registered faces of the first plurality of registered faces and arranged to cast a second shadow of a predetermined shape when the sculpture is positioned at a second angle of rotation about the axis different from the first angle and in the light path directed at an oblique angle to the surfaces;
- and,
- a member connected to the sculpture with the axis of rotation extending through the member and rotation of the member successively brings each pair of registered faces of the first plurality of pairs of registered faces into alignment with the light path.

A system for projecting multiple silhouettes on to a surface comprising:
- a sculpture bound within a volume of a polyhedron having a first plurality of pairs of registered faces comprising:
- a first plurality of plates connected together in parallel spaced relationship with a plurality of spacers, the plurality of spacers formed in a process other than a process that formed the first plurality of plates, to form a first number of layers with gaps between adjacent plates, the first plurality of plates having surfaces extending transverse to a first pair of registered faces of the first plurality of pairs of registered faces and arranged to cast a first shadow of a predetermined shape when the sculpture is positioned at a first angle of rotation about an axis and in a light path of a source of light directed at an oblique angle to the surfaces;
- a second plurality of plates connected together in parallel spaced relationship with a plurality of spacers, the plurality of spacers formed in a process other than a process that formed the second plurality of plates, to form a second number of layers with gaps between adjacent plates, the second plurality of plates having surfaces extending transverse to a second pair of registered faces of the first plurality of registered faces and arranged to cast a second shadow of a predetermined shape when the sculpture is positioned at a second angle of rotation about the axis different from the first angle and in the light path directed at an oblique angle to the surfaces;
- and
- an axle connected to the sculpture with the axis of rotation extending through the axle and rotation of the axle successively brings each pair of registered faces of the first plurality of pairs of registered faces into alignment with the light path;
- and,
- the light source mounted proximate the sculpture.
