Short review: At one of most significant points in the Alps, probably the most important Alpine crossing, on the hill of Bergisel near Innsbruck, above the tree tops, there is a glass cockpit, which looks as though it is sending ‘hellos’ to the drivers of the cars and trucks which pass by. At night, we can perceive it as a glowing mega-fire, as if it should serve as a traffic sign for extraterrestrials.
