about the cover: To create
an image of a wave of data,
german artist Thomas herbrich
photographed over 1,000 printed
pages then reduced them to 6cm
through multiple photocopying.
he then began the arduous task
of adhering thousands of these
miniature pages onto corrugated
styrofoam sheets to create and
photograph this 3d scene.
The effect of flying papers at the top of the wave was
created by throwing hundreds of mini-pages out of a
bucket and photographing them. he then blended the
separate images together to form the wave. for more
about his work, see http://www.herbrich.com/.
