Some of us are more particular about the appearance of our interiors than others - perhaps to a fault. Sick of seeing your books sloppily organized by type, or, worse yet, having them randomly disorganized across a series of bookcases? Sorting your favorite volumes by color may just satisfy that too-organized part of yourself.
Call it art, call it obsession, but the results are a rainbow of awesome to be sure. Some of these were done as personal pet projects but one in particular involved the reorganization of an entire store to fit into one big color spectrum of books. Practical? Perhaps not. Appealing? On an aesthetic level: absolutely.
