Some people at the New York University have created a nice screen where you can interact with by just using your fingers. It is based on the same mechanism used by fingerprinting. Take a look at this movie. It immediately reminds me of the movie Minority Report. Just add some transparency to it. Funny and interesting that things which were in movies a few years or several years ago seem to become reality not that far away from the future. I am sure that a lot of futuristic things in movies — which play in a far future — will be developed/invented much earlier than we can even imagine.

For those who are interesed in it btw, the soundtrack of this short video is from Peace Orchestra and is called Who Am I?.
