This table and set of chairs were created by Bezalel Academy of Arts and Design student Iftach Gazi, and the way that he created them was by getting a big slab of concrete, reinforcing it in specific places, and then hitting it a bunch of times with a hammer (see video). It may not result in the most symmetrical chairs in history, but it is one of the more oddly satisfying methods of furniture making we've ever seen.
