The illustrator behind Android’s cute Google Now backgrounds has made screen-sized versions available for download.
Brent Couchman has uploaded the four official ‘Now Scenes’ to his Flickr account. All of which are available in sizes of up to 1680 x 1050.
So yes, perfect desktop wallpaper material!
Each of the images below links straight to the respective page, so no need to hunt around.
