Mysterious Modular Device comes in pieces and you assemble it yourself. You aren't quite sure what all the pieces do but you know you need all of them for the device to function. The device is an integral part of your life, and so the complete device also completes you.
Mysterious Modular Device is a commentary on what Albert Borgmann describes as the dichotomy between opaque and articulate design. Modern consumer electronics are typically opaque in their design in that it obscures mechanism and function as opposed to expressing it, because of this our cell phones now have capabilities far beyond our ability to understand or relate. Mysterious Modular Device attempts to articulate the seemingly benign but potentially sinister nature of the opaque black boxes we take for granted.
