-Here's the file to list the authors of the pictures, as
-far as I (matju) know:
-
-b001.jpg, r001.jpg:
-  Eyewire Catalogue, 1999 or before. It should be checked
-  whether there still exists a copyright on this, because
-  the original provider has disappeared (bankruptcy??)
-  several years ago.
-
-g001.jpg:
-  by Alexandre Castonguay, 1999 (?).
-
-bluemarble.jpg:
-  NASA (?)
-
-lada.jpg:
-  hungarian newspaper ad.
-
-lena.jpg:
-  Lena Sjööblom Soderberg, centerfold of Playboy 1972.11.
-  Researchers in infographics have extensively used that
-  picture without necessarily asking for copyright, and
-  apparently Playboy doesn't mind.
-
-lucida-typewriter-12.grid.gz:
-  a grid(256,13,7) containing the Lucida Typewriter 12
-  medium font.
-
-opensource.png:
-  modification of a World War Two poster. Both authors
-  (original's and spoof's) are unknown to me. Should check.
-
-rose.jpg:
-  unknown origin.
-
-ruby0216.jpg:
-  photo from a conference about the Ruby programming language,
-  held somewhere in Japan in 2003 or so. (?)
-
-teapot.png:
-  Researchers in infographics have also extensively used
-  that picture (actually the wireframe model). This is
-  (afaik) the original model, produced in the 1970's (?)
-  by one such researcher, and then was rendered in the
-  1990's using the Povray raytracer, and then bundled as
-  teapot.ppm in Tcl/Tk, and finally in 2001 I grabbed
-  that picture 
-
-test.mpeg:
-  unknown origin. Too small to be copyrightable.
-
-tux.tga.gz:
-  unknown origin.
