For the forgetful art lover in your life comes this simple collection of multi-colored sticky notes that when arranged together bear a striking resemblance to one of Piet Mondrian's Composition pieces. But you won't need millions of dollars to adorn your office with this functional masterpiece.

PA Designs is selling it for just shy of $17, which is considerably more expensive than 3M's offerings. But you also won't find a yellow Post-it note hanging on the walls of the Tate Modern. [PA Design via Design Milk]
