Augmented reality is typically associated with apps for the iPhone today with other images overlaid on a live picture of your surroundings. Artist Chris O'Shea has installed a new public art piece called "Hand form Above" in England.
The installation has a large screen with live video of people walking by projected on the screen and overlaid by a giant finger that follows the walkers by and pokes them. I am sure this thing might be disturbing to young kids and possibly old people who hate technology.
The thing is pretty slick though and the only way it would be cooler is if you could put your own finger in the image to do the poking and taunting of people around you. I wonder how much it cost to set the installation up. The inspiration according to the artist came from "Land of the Giants and Goliath."
