I’d seen a lot of this piece on social media and finally managed to visit it in person a week before it closed at Tate Britain’s wonderful Duveen Galleries.
Cerith Wyn Evans created this sculpture called Forms in Space…by Light (in Time) filling the gallery above our heads with neon shapes drawn in space. The structure begins with a circle
then 3 symbols used by opticians for eye tests , also used by Marcel Duchamp in his The Bride Stripped Bare by Her Bachelors, Even (the Large Glass)
followed, as you walk through, by shapes initially inspired by the gestures of Japanese Noh theatre.
You don’t , of course have to view it from front to back; wandering around it gives so many different viewpoints. 
I also wanted to mention the way the whole thing has been suspended – the support has a fascination of its own.
You can see more of his work in London in the lobby of the recently opened Four Seasons hotel at 10 Trinity Square .
