The DAVE is an immersive projection environment, a foursided CAVE. DAVE stands for "definitely affordable virtual environment". "Affordable" means that by mostly using standard hardware components we can greatly reduce costs compared to other commercial systems. We show the hardware setup and some applications in the accompanying video. In 2005 we buildt a new version of our DAVE at the University of Technology in Graz, Austria. Room restrictions motivated a new compact design to optimally use the available space. The back projection material with a custom shape is streched to the wooden frame to provide a flat surface without ripples.
