Spheros arent just fun; they are also an excellent teaching tool. Students have begun using them to learn everything from geometry to genetics. They can code them, too, to take a first step into computer programming. The toys infiltration of the classroom came about mostly by accident. Ian Bernstein and Adam Wilson, the inventors who came up with the Sphero, six years ago, were immersed in hacker culture, and they planned to disseminate portions of their code to anyone who wanted to improve on it or add to it. Eventually, they realized that if the app came with a simplified form of that code, kids would fiddle with it.
