Illuminated Electric City IV
This complex and fascinating piece is utterly unique. Formerly a Rubicon potentiometer built in the 1930s and used at Purdue University, it features an array of different bulb types that may be brightened and dimmed with the knobs mounted on the front of the piece. The central bulb mounted on a circular stand is controlled separately by rotating the handle on the stand. A master knob controls overall brightness of the piece.
Mad Science Effect: A separate switch allows the bulbs to display random flickering, giving the piece a touch of mad scientist energy. The effect may be brightened or dimmed with the Master dimming control, A voltmeter measures the amount of current being delivered to the bulbs while in operation, allowing precise configuration.
Thermodynamic Bubbler included: The heat produced by the bulbs transforms the liquid in the vial to a vapor, pushing the remaining liquid to the cooler top of the vial. It will burble away for hours, and eventually all the liquid will collect a the top. A gentle cup of a hand on the top of the vial will return the liquid to the bottom.

The wiring along the top of the piece is evokes streets in a busy city, with the varying mounts for the bulbs reminiscent of buildings.
This is the only device of its kind, and it is destined to become part of a collector's gallery. It comes complete with a manual of operation.
All electrical circuitry is certified, and the piece is thoroughly tested for reliability and safety. It comes with a lifetime warranty, exclusive of bulb replacement.
