I've had a lot of very lovely Christmas/holiday greetings from some terrific Mac and iOS companies cross my desk this year, but Twelve South's stood out because the company is offering a free gift to everyone. Twelve South commissioned four sets of wallpapers from San Francisco photographer Scott Gordon designed for people with two displays. The one I included is called Nightscape, but there's also Fall in San Francisco, Cloudveil, and Soma. Each comes with a left image and a right image (though any one of them would be great for one-screen Mac setups, too), and they've been formatted specifically for seven different screen sizes, from an 11-inch MacBook Air to a 27-inch iMac/Thunderbolt Display.
