French visual artist Joanie Lemercier shares glimpses of new works in progress that draw on solar rather than projector light. “These photons travelled 150 million kilometers,” he writes about the beam of sunlight used in his lens refraction experiments. “It encompasses the entire electro-magnetic spectrum—visible light, infrared, uv, radio waves, x and gamma rays—and conveys about 500W of energy,” Lemercier notes in subsequent posts. “It’s low tech, yet so much brighter than any high-end projector.”
