Way OT I know, but since Rick brought up the NIN light show of the previous tour, I thought I'd point out that three HD recordings of the shows are available from links on this page
Also, as another example of an amazing use of lighting, check out the Sigur Ros DVD Heima; the live footage is astounding, not to mention that this is one of the most moving music DVDs I've seen in a long time.
