Johnny Lee on the power of video demos

In today’s New York Times, Johnny Lee talks about his clever Wii hacks — and how he shared them with the world via viral video. Johnny Lee’s TEDTalk, in which he shows how to make an interactive whiteboard from a $40 game controller, is a perpetual Top 10 talk on TED.com. Lee’s amazing YouTube videos and his TEDTalk have helped to spread this cheap-but-effective educational tool around the world. From the story:

Some 700,000 people, many of them teachers, have downloaded the software, Mr. Lee says. Much more expensive whiteboards may offer more features and better image resolution, but Mr. Lee’s version is adequate for most classroom applications.
