This is one of the most awesome projection display I have seen. Nokia, together with DJ deadmau5 lights up London night with a 4D projection. You cannot imagine the scale of this projection until you see the video. Enough said, watch this awesome display from Nokia UK.
FYI, I was up at 5am to watch this live streaming. The streaming keep stopping and halting. I guess the server must have overloaded. Anyway, this version is edited and really brought out the best of the event. This is one of the best marketing effort (but not the last) for Windows Phone and it is not from Microsoft.
By the way, if you want to know how they do it, here is some behind the scene moment.
