The following web design/graphic design tool should be immediately bookmarked and shared with your colleagues; it's that useful and interesting.

Repper is a free-to-use pattern creator that turns any image into very attractive designs which can be used as backgrounds on websites or even for Twitter profiles. Users simply upload a random image, resize it and drag the box to change the pattern. Newly created patterns can be saved and downloaded to your own computer.

Patterns generated with the Repper tool are freely available to everybody under the Creative Commons Attribution-Noncommercial 3.0 Unported License.
