Seeing as people here are showing their desktops, let me show you my current liked one.
I usually use 1024x768 resolution, but for the sake of the 56k modem people and to keep this page in size (and also so it fits under the 102400 byte limit), I've temporarily shortened down to 800x600 for this grab.
Try to guess who the girl in the pic is, and you might just win a prize.
