Japanese professor Hiroshi Ishiguro has unveiled an android that precisely mimic a person's expressions. The robot, called Geminoid TMF, can move its rubber face to replicate a smile, a toothy grin, and a grim look with crumpled brows using a motion-capture system.

Unfortunately, Mr. Ishiguro destroyed the doll with a hammer after the eightieth time it said, "No, YOU stop repeating ME!"
