Like I said, my cabinet is based off of the sculpture, but it also has some other interesting aspects. Mine is wall-mounted, has a door and a shelf inside, and has imbedded electronics which control the one-way mirror. The idea is: you put an object in the box which symbolizes your true identity, and an object in the 'forceps' (mine are actually salad tongs) which symbolizes what other people see you as. When the light level is high in the environment (like, the room that the cabinet is hanging in), the glass pane acts like a mirror. However, when you turn the lights down in the room, the light sensor in the cabinet triggers a MOSFET which turns small lights on inside the box, turning the mirror into see-through glass, and letting you see the object inside the cabinet.
The metaphorical implications are endless, and so it was not only fun to build, but also got me a great final grade in the class because my english teacher loved it.
The cabinet and door frame are 4/4 walnut, and the veneer inside is elm burl. I finished the entire thing with danish oil.
The build time was about a week, working in the evenings after school. The cost for all the materials was probably a little under 100 dollars (walnut ain't cheap).
