This is my current wallpaper: http://img594.imageshack.us/img594/8...keblueneon.jpg ...My computer's power light glows neon blue, my Logitech G9 glows blue, my monitor's power light is blue... this wallpaper matches it all perfectly, looks really cool
(Update: I'll check back in this thread and update this original post to add more URL's so we'll get a nice list going for people looking for wallpapers)
