Very interesting. I saw an exhibition he did at Riverbank a long long time ago that was perspex shapes lit up by CRT screens that were showing random (?) colours - all set to very soft ambient music. The hall was pitch black and it took a while for eye to get used to the lack of luminosity - I think that was the best bit because you couldn't see anyone else (kept bumping in to people though) - once the eyes adjusted and you could see more it wasn't as amazing, but good nevertheless.
Sit, contemplate, relax. It really did me a lot of good, I came out incredibly refreshed!
