The puzzle consists of laser-cut wood pieces and acrylic windows. The windows have channels in them, through which the metal pegs can pass. The metal pegs and channels allow the user to move the pieces around in the frame. The objective is to remove the pieces, then arrange them by inserting and sliding so that they fit back into the frame. Made in laser-cut wood, acrylic, and stainless steel by Jean-Claude Constantin.
