5. Lego’s Mindstorms Robotics Invention System was designed for 12-year-olds. But after more than a decade of development at the MIT Media Lab using the latest advances in artificial intelligence, the toy created an enormous buzz among grown-up hackers. Despite its stiff $199 price tag, Mindstorms sold so quickly that store shelves were emptied two weeks before its first Christmas in 1998. In its first year, a staggering 100,000 kits were sold, far beyond the 12,000 units the company had projected. Seventy percent of Mindstorms’

early customers were old enough to vote. These customers bought the software with the intention of hacking it. They wanted to make the software more flexible and powerful.

They deciphered Mindstorms’ proprietary code, posted it on the Internet, began writing new advanced software, and even wrote a new operating system for their robots. To date Lego has done nothing to stop this open source movement, even though thousands of Lego’s customers now operate their robots with software the company didn’t produce or endorse and can’t support. The software may end up damaging the robot’s expensive infrared sensors and motors.28
