This flexible bookcase, called Squaring, has been created by Korean designer Lee Sehoon. The piece is comprised of nine square units that are hinged together in a circle. Thanks to this unusual contraction, Squaring can expand from the initial neat grid mode to a number of dynamic shapes, thus increasing its storing capacity. It is also interesting to observe how unequal wight distribution changes the appearance of the bookcase, making it an interactive object, capable of unexpected transformation. Check out the video after the break to see Squaring in action.
