Hip to be Square

Some 2200 years ago Archimedes invented 14-piece dissection puzzle similar to tangrams. It is called the Loculus, Stomachion, or Archimedes’ Box. The object is to rearrange the pieces to form a square. In November of 2003 Bill Cutler used a computer program to find the 536 distinct solutions. If only Archimedes had been around to see this!
