—AIN`T NO SUNSHINE, 2004 / 2005 Public art competition, realization with QUIVID (public art program, City of Munich) solar controlled light installation in the entrance hall of the Kindergarden Riegerhofweg, München-Laim LEDs, acrylic glass, solar cell, controller system < Back Aint no sunshine is developed for a public art commission in a kindergarden in Munich and tries to integrate the children as well as the pedagogic program in a participatory process. An abstract drawing is developed through drawing and playing with a big neighborhood map, neighborhood walks and told stories in which the children describe their daily way from their homes to the kindergarten. The abstract line net as a cartography of their daily walks is used as a draft for a light installation on the ceiling of the new kindergardens entrance hall. It consists out of yellow light rails that form an individual map of the neighborhood with the kindergarden building in the center. The light is animated in relationship to the photovoltaik solar system on the roof of the building. In eight phases the light in the line web is growing or shrinking depending on the solar energy that is gained. When the system reaches 100 percent the light drawing starts blinking. Thus it functions as an extended display of the solar system and the daily walk way of the children becomes a metaphor for gaining and using energy.
