Thanks to Norm for sending me this wallpaper art.
Andreas found the artist via TinEye: Staszek Marek. It has different sizes (I got one for my Cinema Display, perhaps the size reads the screen size of the visitor.)
I have always been fond of SF imagery, especially urban. As an example, my favorite part of the fourth Star Wars movie (Phantom Menace) was the great city scenes, like the street view with the café.
