2 big books in a slip case: volume one contains very many pages with incredibly many dots on each page. We are to understand that each of these dots represents one second of the time it takes the earth to once orbit the sun. The second volume contains again very many pages with each incredibly many parallel lines. The length of all those lines together represents the true distance covered by the earth each second (or dot of the former volume) on its way to orbit the sun, soft cover, measurement of slip case: 28 x 27 x 8,5 cm, 2nd ed/100 copies, (the 1st edition consisted of 50 copies actually made), Aachen München 1982
