Today, I hacked on that script, queried YWS on a set of keywords, and generated a wallpaper from the collage.

You can download the wallpaper, by clicking on the image above. The wallpaper contains image search results for the following keywords:
* face
* tree
* giraffe
* lion
* zibra
* flowers
* red flower
* yello flower
* sky
* ice
* fire
Isn't it beautiful?
