Pipe Organ Desk With Programmable Pneumatic Logic Controller, Secret Compartment

I first wrote about Denver puzzlemaker Kagen Schaefer’s gorgeous purpleheart butcherblock benchtop two years ago, and now Kagen’s knocked me out again with this nigh-unbelievable desk. It features eight working wooden organ pipes that play notes when when you push in the various drawers, and also a pneumatic computer that records the sequence of notes and, when the right melody is played, opens a secret compartment. The pneumatic lock can be reprogrammed to recognize any melody. Holy smokes.
