it would have been cool to see
i don't think he could have used a screen because you need to sit in a certain angle for this effect to work, don't you think?
so some of the audience would have seen what he wanted, while the rest wouldn't.
i was thinking about lights or something that could create a 3D image of those wings... now i think that that could have been seen by everybody... he just needed to sit in the right spot to create this effect ... but i'm just speculating on this one
we will see on the live DVD i hope
i wish he'd do documentary of "The making of XYZ tour" ... a behind the scenes thing ... but more complex... a complete one
i think that it would be really interesting to see the technical side of what it means to have a live concert
edit:
done, i've asked someone who attended lives in his tour
they were on the screen behind Gackt ... so they used a screen to create that effect
that must have been amazing to see
