SignalToNoise, kinetic sound installation
It doesn't feel like that long ago that we'd hear the flapping noise of the information displays at most train stations and airports, yet quietly, and almost unnoticeably, they have mostly transitioned over to LED monitors. Belgian artist team LAb[au] consisting of Manuel Abendroth, Jérôme Decock and Els Vermang, created a playful type installation for Toronto's Luminato Festival last year, utilizing the discarded technology and salvaged split-flaps from these old signage systems, arranged in a circular grid. Signal to Noise, as the piece is called, takes the random letters from the illegible and nonsensical into the legible and poetic, through its flapping mechanism. Apparently the sound is much subtler than in the video below; almost like rain.
