Background sampler
Feel free to nab any of these backgrounds.

My only stipulation is that you email me the URL where I can have a look at my creations. Each thumbnail can be clicked to view a preview on an actual (but simple) page. The latest browsers make it easy to get them, just right click on the image desired and hit "Save this Image as...". Please, no mirroring!
