The Sixth Sense

This is something I stumbled on not too long ago and (as a big of a technology geek) it blows me away what people have been able to create! What I like most about 'the sixth sense' is that it isn't much more than a camera and a connection the the internet but has amazing abilities. This doesn't have a whole lot to do with advertising, but I definitely think that it demonstrates creative solutions to the current limitations of technology.
