Several friends passed me the link to this TED video. If you have not seen it yet, give it a view. This may be where personal tech is going over the next few years.
A friend passed me the link to Woody Norris’ chat at TED. Some neat ideas. He talks about the concept of focused sound although you won’t hear the effect of his waterfall demo. But the idea that sound can be focused like light is very interesting. And the concept that we have only just begun to invent is also interesting.
