As part of the course "One thing one light" students of the Faculty of Architecture have designed different lamps which, according to our counter-entropy concept, consist of different re-use materials. Within a few weeks about 40 participants developed their own design of a standing or hanging lamp and finally presented them illuminated in the basement of the faculty. The lamps are made of film cans, clothespins, old fire hoses, plastic cutlery, yogurt cups, egg cartons and bottle caps. Despite the great results we do not yet know, which lamps we are going to integrate in the interior of our building. We plant to show the best designs separately on our website later.
