City Lights - who doesn't know them? Whether as a free-standing showcase, a column or integrated in a waiting shelter, the City Light posters behind the glass panes are highlights that brighten up the cityscape on roads and streets, squares and stations and make everyday life a little more colourful. They attract attention with creative and high-impact motifs. Special designs and applications catch the eye, whilst playful technical features enable interaction with the contact-happy public of the Digital Native Generation. City Lights are a tangible medium that is particularly close to people.
