Via Dezeen, a funky but cool installation at the London Design Festival 2013.

Fluorescent lights are controlled by analogue toggle switches in this interactive installation by Faye Toogood for design brand Established & Sons (+ slideshow).

“Interactive” for sure, but no computers were harmed in the making of this installation!

That gorgeous background material is “iridescent zinc passivated steel – an industrial material used to provide insulation from electrical interference.”
