PingMag has a fun piece up on the upcoming 21_21 Design Sight — a dream design project that brings together such luminaries as Issey Miyake, Taku Satoh, Naoto Fukasawa, and Tadao Ando. The logo, designed by Satoh, is now up on the project’s official site, ready to be played with (see what people are doing with it at this Flickr group).
