The photography duo of Floto+Warner created the series, “Colorant”, from an idea that stemmed out of a previous series and the fascination of landscapes, with results that leave one in awe. Creating shapes, not experienced in nature, they tossed colored water in the air to capture “a momentary graffiti of air and space”. Using a high shutter speed to capture these fleeting moments, Floto/Warner has produced a multi-medium series with jaw-dropping results. Photo: “Orange Salt Flats”. (Photo by Floto/Warner)

Wedges of an orange generate enough current and electrical juice – 3.5 volts – to power an LED.
