Light Show at Hayward Gallery

I've heard only good things about Light Show at the Hayward Gallery and really want to go, it's on until 6th May. The exhibition features sculptures and installations that you can move around, and through, to experience light in all of its spatial, sensory and mind-altering brilliance. Some of the artworks date from the 1960s and have been re-created specially for this show. Have you been? How was it?
