"Berman and his colleagues have zeroed in on the “low-level” visual characteristics that distinguish natural from built environments. To do this, they broke down images into their visual components: the proportion of straight to curved edges, the hue and saturation of the colors, the entropy (a statistical measure of randomness in pixel intensity), and so on."

I wonder whether these principles could be incorporated into architecture and interior design, so we feel like we're in a natural setting even when indoors.

(Even better with trees visible through the windows, of course.)
