Gimp-texturize is a plug-in for the GIMP, a famous picture editor and manipulator. . A few images are designed to be copy-pasted one next to another and still look natural, but the result is usually periodic and very monotonous. The Texturize plugin allows you to have a realistic pseudo-periodicity. . Have a look at http://www.manucornet.net/Informatique/Texturize.php to see how it looks like.
