Troika was commissioned by Artwise Curators to create a signature piece for the entrance of the new British Airways luxury lounges in Heathrow Terminal 5. In response, we created 'Cloud', a five metre long digital sculpture whose surface is covered with 4,638 flip-dots that can be individually addressed by a computer to animate its entire skin. Flip-dots were conventionally used in the 70s and 80s to create signs in train stations and airports. By audibly flipping between black and silver, the flip-dots create mesmerising waves as they chase across the surface of ‘Cloud’.
