Niggli Puzzle

"niggli.puzzle" is a new challenge for the sporty eye. Unlike traditional jigsaw puzzles, in which the shapes of individual pieces assist the eye, it features only two forms: square and circle. In this way, it is not evident which pieces belong to the border of the image, which makes the solution of the puzzle more difficult. All pictures represent materials: small-sized textures of wood, glass, paper, and metal in great numbers. All five jigsaw puzzles have this in common; similar forms are repeated many times without ever being exactly the same – an additional challenge to the accuracy of perception.
