Ephemeral Rays by Charlotte Smith is an art installation that revolves around a multitude of incandescent light bulbs. But it isn't one's typical light installation, although it does explore the matter extensively. Instead, it focuses more on the play between light and dust as a representation of the passage of time and historic significance of a place. In this case, the Chatham Historic Dockyard in the United Kingdom.
Comprised of countless of light bulbs strung from the ceiling, Ephemeral Rays by Charlotte Smith invites peoples to take in the "small particles of dust can be seen drifting through the beams of light, while the light refracted by the hundreds of bulbs exists as an echo of each fleeting ray," as written on My Modern Met.
