Bus stops involve people waiting, which makes them a perfect location for a work of art. In the Oosterstraat a news ticker has been installed between two stainless steel columns. Instead of passenger information, texts are displayed about travelling, buses, and heart and lungs. The texts were written by author Jacques Brooijmans and most of them are poetic or philosophical. In the Oosterstraat is a transparent synthetic heart in neon light above the columns. In the Gelkingestraat, that runs parallel to the Oosterstraat, lungs are placed above the columns. The organs refer to the centre and periphery of the city. When you enter the city by bus, you first pass the red heart, a symbol for the centre and the dynamic liveliness surrounding it. When leaving the city via the Gelkingestraat, buses pass the green lungs that refer to the tranquillity and space in the suburbs.
