I visited a light art installation by Anthony James which is currently being shown at Marble Arch. It’s called Light field. I really enjoy light art, especially if creates optical effects.
Looking into the hexagonal shapes made it look like the space went on forever. There was a similar styled longer shape too. I also liked the square boxes, all placed in a uniform way. The boxes changed colour in time to some music being played, which I found quite relaxing to watch.
The exhibition is at the Mound and is free. Worth a look I think.
