My niece's husband Dan is a director of a light & sound art installation company called Squid Soup. They have an exhibition on in Bristol at the moment called "Beyond Submergence" ("Submergence" is one of their best-known installations, which we first saw as part of a Christmas Lights trail at Stourhead in 2019).
This image is "Sola", commissioned by St Thomas' Hospital in London - Dan did the initial design work.
