Jongha Choi has a simple storage solution for your small apartment: Turn your unused furniture into wall art.

For his master’s thesis, Choi, who recently graduated from Design Academy Eindhoven, created benches and stools that lay flat but pop open. He calls it De-dimension, and it’s flatpack with a perceptual twist: a perspective drawing come to life, its planar form conveying the height, width, and depth of the "assembled" stool. In the video, Choi pulls one from the wall and, with a smooth, quick gesture, opens it like the page of a pop-up book.

Click over to Choi’s website and you’ll find that his furniture is the physical embodiment of a thesis exploring heady ideas about perspective and how we perceive the similarities and differences between 2-D and 3-D objects. "If our perception of an object is not different on a plane image and an actual subject," he asks, "isn’t it possible to substitute the two with each other?” In the case of De-Dimension, the stools and benches are never truly 2-D; but the fact our brains can appreciate their dimensionality, even when flat, is a clever visual trick that would earn Choi an awful lot of money if he decides to sell his designs.
