The Rollbuch is an object with roughly the size of an ordinary book. Inside, there is a long paper band wound onto two spools, which can be moved in either direction. Printed content thereby passes smoothly in front of the viewer, without breaks and without ever turning a page. The motion of the paper, together with the "infinite" format yield a reading experience unknown from common books or even antique scrolls.
left handle counterclockwise: paper moves to the left
right handle clockwise: paper moves to the right
bottom side: sliding lid to swap paper bands
A Rollbuch may be read from left to the right, or also vertically; it may contain text where everything but a few lines remains hidden. At times it will apply optical illusions to intensify the viewer's sense of motion... – subtle effects we are constantly trying to refine.
