The one that makes you see double.
Clemens Habicht’s Changing Colors is a color gamut jigsaw puzzle of 1000 pieces in which each individual tile has two distinct color states from intersecting gradients of color. Printed using a lenticular lens, the colors change depending on the angle of view, resulting in a radiant iridescence that shimmers in beautiful color combinations. "Each piece reveals and hides itself constantly until spatially locked into place.”
1000 ribbon-cut pieces, the puzzle measures 26.9 x 18.9 inches when completed. Made in Poland from a lenticular lens mounted on greyboard. The difficulty level of this puzzle is hard.
