This is an optical illusion called a Penrose triangle. Each of the 3 pieces are the same size. Each piece should also be a different wood to reinforce the effect. I used walnut, maple and alder. It would have been better if the alder would have been a little closer to the walnut.

This should be relatively thin as a thicker artwork would lose some of 3D effect. The cut time is minimal, but the finish and sanding adds to the overall time required.
