Kagen Sound is a woodworker in Denver. What he's made here is a desk and much, much more. It's covered inside and out with puzzles. Those puzzles open secret compartments and activate hidden features. He says that there are at least 20 of them, with at least one in each drawer.
The workings of a pipe organ are hidden inside. It has a memory board that is programmable by shifting wooden blocks. To play the organ, open and close the drawers in sequence. This pumps air into organ. You can see more photos showing the internal components of this incredible work of craftsmanship here.
