What wallpaper do you currently have?
Mine
I’m psyched that soon we should hear news on the fourth entry.
On the netbook it automatically rotates between these. Had to crop 'em though. :twisted:
On the gaming rig I’ve got this one. Don’t open it. 
I’ve got one of the default Windows 7 wallpapers, the one with a waterfall. I used to change wallpapers often when I was younger, now I don’t really care about this stuff.
I use Windows 7 shuffle wallpapers with Rosairo + Vampire.

I’ve had Lacus Clyne as my comp background for several years now. Still haven’t enountered anything I’d like to put there more…
On my desktop, I have the NASA Hidden Universe Theme, mostly because I’m too lazy to really search out something else to use. On the other hand, my laptop is using a Sora background (i.e. from Yosuga no Sora). While were on the subject of the way we decorate our computing experience, I’ll add in that I’m using a Mio Akiyama (from K-On) theme for Firefox.
I changed today. Sadly, It doesn’t fit my monitor so distortion fail. Make me a bigger Sega.
Mio theme FTW. But I have the viewing area maximized in Firefox, so themes are not usable for me… ;-(
