Tonight I went to see the Photophonic Experiment at the Queen Elizabeth Hall. The basic idea of the show was the interplay between light and sound, using light sources to generate noises. If that all sounds rather esoteric, the result wasn't: There's a very simple delight in hearing sounds resulting from flashing or moving light, and the sheer playfulness of the project came across wonderfully. Well, I enjoyed it, anyway. Sometimes it's good just to revel in sound.
