The Minority Report is becoming more real everyday. After the spiders, now the touch wall. Would be nice to have the cars next (and not the eye-scanning everywhere)

It is becoming rather crazy, and in 30 years think about how small they could make the devices need to do the touch screen technology. Just look at how small computers have gotten over the last 30 to 40 years. We’ll probably be able to turn any window or wall into a touch screen with a device the size of a deck of cards.
