Sometimes I like to do a wallpaper search to see how people have used certain graphics applications. Today I tried 'Illustrator', and received a batch of mixed graphics and photographs. I believe the graphics were all from the 'Illustrations' category, while one photo used the word 'illustrating' in its description, and another used the word 'illustrates'.

Hmm. Would still like to be able to search just for 'Illustrator' wallpapers. :-)
