On Sat few people from my year and I went to this installation called 'field' by Richard Box. It's an amazing experience and you have to go if you have a friend, a torch and a car. Thousands of fluorescent tubes are planted at the foot of an electricity pylon, and as the night comes you start to notice the flickering tubes. The tubes are not at all 'connected', they are simply stuck into the ground, but the electricity jumping off the pylon is enough to light the tubes. If you stand close to one, the glow fades as the electricity is now passing though you other than the tube (scary thought..I know). But the installation points out beautifully what we would never notice, and its just a stunning piece of work.
