Manufactured with the specialized lenticular printing process, Visual Echo puzzles display the illusion of depth and movement when viewed from changing angles. Parallel rows of optical lenses display different facets of a complex, interlaced image underneath the top layer. The “You Are Here” puzzle, once the 500 interlocking pieces are assembled, features the planets of the solar system drifting on the star-filled background of space. 
― “Visual Echoes is a line of 3D puzzles that does pretty well. I'm looking at the line right now, and it's very good,” Robin Ellerman, owner of Trains-N-Toys in North Canton, Ohio, told TDmonthly in June 2009.
