The work PC I brought home has two monitors. The same wallpaper on each screen looks silly, so I went over to Digital Blasphemy and snapped up a bunch of dual-screen ‘papers. The six shown here are just a few of the many I downloaded. Beautiful stuff.
They’re not free, but for $15 you get 90 days access, which means you could easily download everything there. It also means you generally don’t see this wallpaper on other machines, keeping your PC unique. I’d say 75% of the wallpapers on my Macs and PCs are from DB.
