In a time where physical contact has become an exception, the telephone is having a renaissance as a medium: We talk to our banks, order food or find us talking to a call-center on the other end of the world. But what about visiting an exhibition through the phone? The students from the art-department developed an exhibition where the artworks are a service, accessable only through a phonecall. The book „Slightly yellow pages“ accompanied the show in a triple-roll: Invite, floor plan and documentation at once.
