Who deals with light has also to think about the night in general. The project ‘at night in darmstadt’ tells all kinds of stories around the night in an innovative way. From Darmstadt, from the science, from unusual points of view. The book will be introduced on the 30th July at 19.30 o’clock in the jazz institute of Darmstadt. Josef Mayerhofer and his friends will consider whether and how they could run a project for the Luminale in 2010.
