We love the ingenuity and whimsy found in Phillip Don's Stand Up Desk. Sleek, white and minimalist, the desk features wooden bars along the back of the desk that can be flipped up to serve as book ends, a back rest so items don't fall of your desk or even note holders (each bar has a slit along the top).
Phillip Don is a Korean born designer who recently exhibited his "Stand Up" collection DesignTide during the Tokyo Design Week 2009. The collection also features a stool with a top made of wooden bars. Alternating bars can be positioned to create a chair back.
