The goal of this book is to develop temporary light spaces that re-interpret the existing urban environment on a seasonal basis or over a cycle of several years. As a result, the city will literally appear in a new light. Strollers in the city streets will experience their familiar environment in a new way. Illuminated planes interlacing with planes made by linear fields of light beams will create immaterial material space experiences: still lifes of light within which one can move about and light choreographies that move barely noticeably, creating still lifes in motion.
