MOZANIAC is a patented, expandable picture-puzzle system in which the same flat, modular puzzle pieces can make four or more pictures. Everything depends on how the pieces go over and under each other, revealing and hiding part of what is printed on them. Each completed picture holds itself together as an integral unit until it is taken apart to form the next picture. MOZANIAC is the most important development in picture puzzles since John Spilsbury invented the jigsaw puzzle in the 1760s, according to Daniel Young, founder of Paradoxy Products. MOZANIAC presents new visual and physical challenges of a very high order. The first series of puzzles makes four different pictures with the same six pieces.
