A puzzle, solved by arranging scrambled visual information in a predetermined visually recognizable pattern, is provided. In one form, the puzzle comprises a plurality of puzzle pieces arrangeable to form at least one surface according to said predetermined visually recognizable pattern, at least one of said pieces bearing a reflection hologram designed to reconstruct a first form of visual image information when observed at a first viewing angle and a second form of visual image information when observed at a second viewing angle, said first and second forms of visual image information being "different in type". In another form, the present invention provides a puzzle comprising a plurality of puzzle pieces arrangeable to form at least one surface according to a predetermined visually recognizable pattern, and wherein at least one of said pieces bears a reflection hologram designed to reconstruct visual image information, the peak angle of reconstruction being substantially normal to said surface.
