some one showed this to me over the weekend and i can't stop thinking about it. i really appreciate the fact that they're trying to keep the cost as low as possible because it shows that they are actually trying to create positive change and not simply looking to make a quick buck. this amazing technology could really affect the way we live our daily lives, shop, travel, and even socialize - that tag cloud when you meet someone is slightly controversial but hysterical none the less. to say that its potential is exciting would be a serious understatement. TED rocks.
