i dont think its the one showed on the video....but i think it would work on the same principle...on the video the man said it was a prototype...so obviously they havent finished the full working one...this could be because of the touch screen the one coldplay have prob doesnt have a touch screen as its not needed so that might be the reason why they have already got the Magic Balls up and why microsoft are on (still) on the prototype stage
Gravity release me
And dont ever hold me down
Now my feet won't touch the ground
The magic balls definitely were not using Mircosoft's Surface Sphere. I was at the concert in Philly. The balls were most likely inflatable or plastic, with a projector inside (at the top). The concert was absolutely FANTASTIC by the way!!!! It was something I will never, ever forget. My life is now complete...haha. They have a way of making a sh*t day/year, feel not so sh*tty.
