Twelve South, the clever makers of some of our favorite products, also happen to offer a series of dual-screen wallpaper collections for MacBook, iMac (including Retina), and Apple Cinema Display. If your setup includes a MacBook, use a HiRise adjustable stand for best results.

As of this writing (August 20th, 2016) they've gathered four wallpaper collections thanks to the help of photographer Scott Gordon and their in-house visual artist Steven Jones:

• Collection 1: Fall in San Francisco
• Collection 2: Scotland, Summer to Sea
• Collection 3: San Francisco Sky Lights
• Collection 4: Hawaiian Island Adventure

These backgrounds are 100% free, so go grab them all at Twelve South.
