Kami Robo!

Kami-Robo are robot fighters made from paper, measuring 15 to 20 cm. high.  They have joints at the hips, knees, shoulders, elbows and waists which allow them to bend and move quite freely.  About twenty-six years ago,  Tomohiro Yasui started designing and making these fighters, creating an extensive mythology and heirarchy in the process.  They fight in a ring, but it totally tops pro-wrestling with its drama and keen moves.  NOW the whole world is kami-robo crazed.  You can build your own, or even buy ready-made ones if you are a tad lazy -- or in a hurry to join in the fun (so far the only place we've found them is at the MOMA store.  There's lots of great videos on the web too.  This one below gives you a good intro course on their whole story.
