Anamorphic sculpture is a three-dimensional artwork engineered so that its form looks distorted or abstract from almost every position and resolves into a coherent, recognisable image only from one exact viewpoint, or when reflected in a polished mirror. It extends anamorphosis, a five-hundred-year-old drawing technique, out of the flat picture plane and into physical space. Making one is an engineering problem as much as an artistic one. The artist first fixes the vantage point and the optics, then works backwards, calculating where every fragment of material must sit so that, from that one line of sight, the fragments align into the intended figure. Move a few degrees and the illusion collapses back into apparent chaos. For Jonty Hurwitz this is a primary mode of expression. His anamorphic sculptures, many resolved through a cylindrical mirror at their centre, have been exhibited solo at science museums across six continents, and use the viewer's own act of searching for the resolving viewpoint as part of the work's meaning.
