The Dual System Deutschland, a company which is responsible for the reuse and recycling of packaging in Germany commissioned the Stuttgart firm Atelier Br ckner to create a pavilion at the EXPO2002 which would reflect the company's vision of combining the product cycle with the environment and use of resources in a responsible way. The journey through this cycle is represented visually through the architecture and staging of the pavilion. Living plants, real objects, information, light and sound are brought together and provide an exciting backdrop for the dramatic highlight-a 25m high tornado which was generated every hour. This book shows primarily creative process leading to the final design and architecture of the Cyclebowl. Enhanced with technical details of the innovative facades, the publication is a fascinating documentation of architecture as a means of conveying ideas.
