dual-monitor setup. But we spotted this image on Flickr and love how it breaks all the rules... Rather than extending one panoramic image across the two screens or just going with a simple, unfussy repeating pattern, this user decided to go with mismatched—but coordinated—desktop art. Two landscape pictures, one of a green field of grass beneath a blue sky and one of a dark lake surrounded by woods, seem united because of identical color palettes and image treatments. It makes sense when you think about it. Just like picking out throw pillows and window treatments, you're free to get a little crazy with disjointed patterns and prints as long as you keep everything within the same general color families.
