Check out this beautifully crafted 13-piece block set designed by Kengo Kuma - the (legendary) Japanese architect recently tapped to design Tokyo's controversial National Stadium. Light, wooden and soft to the touch, each four by four inch component is made of cedar from Japan's Miyazaki Prefecture and notched at the tips for easy stacking. You can order your own set for $70.
