Well, when I first started messing around with them, I noticed that the images could be changed. I thought it was pretty neat, so I personalized it.

I replaced the image on a gmail widget, and i replaced the image on the tile game widget. I plan on doing this kind of thing to all the widgets I usually use, so that they match up to the backround.
Oh, and if any of you wants me to/or tell you how to replace the image, just tell me. I'd be happy to remajigger your widgets.
