The first time I heard about this technology, I knew it was a keeper. The amazing thing about this "sound technology" is it's ability to give us silence as much as sound! Imagine not having to hear things you don't want to. There is so much noise pollution in our world today, and directional technology such as this could really help eliminate that! The uses are endless as Woody desribes. Note: This was filmed in 2004, but since it's been recently posted again on TED, I thought I would link to it. Check it out!
