Paul Klotz is a Dutch applied art engineer and lighting designer who makes crazy light installations under the name of LED-Art. Tunnel Vision is a tribute to Tesla and is a 15-foot-long sound-and light sculpture that changes when you put your hands in the opening—sort of like an audio-visual theremin. Tunnel Vision's shape is, apparently, based on an abstraction of the 100Hz tone made by electrical generators and is known as Magnetostriction. [LED-Art]
