It may look like a beautiful wood desk [1] but it's also a puzzle box [2] (or rather, a series of puzzle boxes) wrapped around a pipe organ (link via Hacker News [3]). Play the right tune (which can be changed and is stored in memory board made entirely out of wood) and a secret compartment will open up. There are other puzzles that will open up more secure compartments as can be seen in this demonstration [4].
Unfortunately, it is one of those pieces of furniture where if you have to ask the price, you can't afford it.
