Penrose Triangle Marquetry

My latest woodworking project was to do a simple marquetry top for a plain wooden box I had. I've always like all of Escher's Impossible things, and thought the Penrose Triangle would be a nice, and simple project. I actually spent more time choosing the veneers to get the right shading effect, than it took me to do the cutting! I applied several coats of gloss poly on it to give it a durable finish since the box will be handled quite a bit.
