Secret Compartment Pipe Organ Desk

Kagen Schaefer created this Pipe Organ Desk. The notes are played by closing drawers on the back side. Each drawer pushes air through the pipes and plays a note. There is an pneumatic logic board that remembers the order of the notes. When the correct order is played, a secret compartment is unlocked. The logic board can be programmed to unlock when any song you choose is played.
