I found a keeper. Got this from Dragon Magazine, can't remember which one though. I've had it up for a week or so and I'm pretty sure I'm gonna stick with it:
Currently a picture of fire. I change it whenever an especially cool image strikes me- sometimes it's pretty random stuff. A lot of the time it's an astronomy pic (yay Hubble, sad to see it go); once it was an aerial photo, a couple times erotic/sexy pics.
My father is an artist and does a kind of geometric landscape impressionism. I have scans of a lot of his paintings and switch which ones I use as my backdrop every month. Here's the current one.
Work = picture of my husband and I on our honeymoon.
Home = maiden family scottish crest
For sounds = my husband was being cute (in that two year old way) and placed the sexy voice female that says things like "You have mail, master" on MY computer.
