Made of Walnut and Cherry with brass hinges and hardware. The idea to use Cherry was a last minute decission after seeing Matt Cremona's Sofa table - https://youtu.be/atL5A8DzNi4. The Cherry will darken over time and won't be as loud as it is right now.
The compartment is hidden in the top support and is roughly 1.25" deep. The top is released by pressing the top left button in which releases a pin anchored into the top. The five other buttons were disassembled and are just accent pieces. The buttons were off the shelf items from Lee Valley. I would have made my own buttons, but couldn't find a small metal lathe in my price range before the deadline of the contest. The finish is Circa 1850 Paste Varnish.
