a large asymmetrical dome, of plaster, built into the ceiling, almost a metre tall and equally as wide, and, within, the light. it is not easy to describe, you have to see it, standing below and looking up, observing its shape and trying to discover where the light comes from. inside, a combination of led lamps with an rgb control system and fluorescent light fixtures provide coloured light from blue, to red, to green, to yellow or white, every shade of white: ice, silver, cream, ivory.
