An anonymous reader writes "Scientists at Cambridge University have used Lego Mindstorms robots to create an artificial bone-like substance. The toy robots proved to be much easier to set up and vastly more economical than more high-tech solutions. Their research is featured in a video for the 2012 Google Science Fair."
The Tao is like a stack:
the data changes but not the structure.
the more you use it, the deeper it becomes;
the more you talk of it, the less you understand.
