Visual Studio is considered to be one of the best development environment in the industry. With VS2012, Microsoft tried to align its UI with metro design principle. They also changed the logo of VS2012, reducing all its chrome and making it all plain violet. This new logo still looks modern and simple. I was aware of the wallpapers having VS logo with the tag line "life runs on code" ( just google images for "life runs on code" ). However I did not found any with new VS logo. So tried to create one with new logo at HD and FHD resolutions. Wallpapers are quite simple and minimal. Just have a try.
Find all of them in my SkyDrive folder http://sdrv.ms/On9RK5
