A nice picture of a Japanese bridge and lots of greenery. As you can see below, I usually prefer something a bit darker, but this can be soothing occasionally.
My first theme. Undertaken because I just love that KMFMS artwork.
This one is based off of a just-plain-cool pic of a sci-fi soldier that I found linked off a slashdot story and just had to keep in view for a few days. The background pic even provided the menu, tile, and resizebar pixmaps.
