My parents just caught this at Las Vegas last weekend. Holy sh** this is cool. My mom took me to see Queen in 1980 when I was a kid, and called me all excited about this. She told me how halfway through the screens turn into the rows of red/green/yellow lights "like Queen used to use," how all the members' names show up in time with the music (it's hard to see here...it's during the "on and on and on and on" part of WATC, with a different name for each "on"), all the album covers flying around, etc.
She said it's impossible to capture perfectly on video obviously, one of the coolest parts was the stomp/handclaps at the beginning of WWRY because they could feel the bass hitting them from all around.
There are several videos of this on YouTube and I haven't seen them all, but so far the one below is my favorite because of the angle...I like how you can see the fire shoot across the screen at the beginning :) http://www.youtube.com/watch?v=nf4v8MnlWpo
(PS: Has Brian seen this? I just e-mailed him but maybe this is old news(?))
