I used to be quite a desktop wallpaper freak. Minimalistic and abstract was my thing. My favorites use to be 2advanced. But then I cooled of, flirted for a while with Pixel Girl and tried to grab something from DeviantArt, but nothing convinced me. So I was wallpaper-less for a long time. Performance was my excuse. But today I found Vladstudio via DownloadSquad and my desktop shines once again!
Not all of their wallpapers are free (duals aren't) but well worth the money. I'm gonna stick with free ones to see if I can sacrifice that bit of performance for a nice desktop I only see once a week or when I reboot my machine.
