Thanks a lot for the ongoing nice comments on these images, Andras!
It is a 3D-matrix of color lamps, an istallation at the railway station of Zurich, which as always should enhance the fruitless efforts of that village to look metropolitan! ;-) They just connected a computer to the lamps, that controls them and creates some shapes - great deal, you see! ;-) It has already been done countless times by kids all over the world some centuries ago, and now Zurich is very proud to use a bunch of money for installing such a trivial thing as the quintessence of arts and technology! But their banks have enough money though they live somewhere in the 19th century! ;-)
So, I just thought, let's let it look a bit more expensive through addition of even more lamps by superimposing more of them. "More" is always good in Zurich, you see. ;-)
