A metaphor for life, I guess. Jeremy Hsu writes in Popular Science that Hiroo Iwata of the University of Tsukuba in Japan has developed robotic tiles that sense what direction a user is going in and move ahead to provide a place to step. With further development, it could be used in virtual reality simulators in order to imitate movement over distance:
The robot tiles emerged as the brainchild of Hiroo Iwata, a virtual reality researcher at the University of Tsukuba in Japan. A touch-sensitive conductive fabric covers each robot and gauges the pressure applied by a walking person’s foot, which goes toward predicting the next step.
Ultrasonic sensors also help relay position and orientation of each tile back to a central computer that acts as the conductor. It’s an oddly serene robotic ballet, even when two tiles have queued up to move down the line.

Researchers at the University of Tsukuba in Japan have broken the record for the number of calculated digits of the constant pi:
The T2K Tsukuba System is a 640-computer cluster with a processing speed of 95 trillion floating-point operations per second. The T2K calculated a total of 2,576,980,377,524 decimal places in 73 hours 36 minutes, which is a small fraction of the 600 hours taken by the previous record holders—Hitachi and the University of Tokyo—who calculated only 1.2 trillion places.
