Last weekend we had this screening in Berlin. We screened all qualified players of the Masters Cup in Shanghai on two walls at Checkpoint Charlie. It was really fun to work with these heavy-duty projectors and see the results on the wall.
For example Roger Federer (in front you see the historic border between FRG and DDR - the sign on the right side says: "You are leaving the american sector!"):
We showed him the pictures and he said: "“These huge projected images are overwhelming. At this historic location a fine symbol for our worldwide sport.”
