Your Blue Room has an awesome, if somewhat technical, article about the visual production of U2's Elevation tour.

Jodi and I saw the show in DC at the Metro center, and I can vividly recall each effect discussed in the article. As all good shows go, I didn't think much about the lighting during the show, but am amazed now to see what goes into it all. [via u2log – congrats on the bloggie!]
