Giant hand torments city goers

Here’s an excellent use for a giant LED billboard: a crazy augmented reality installation. The appropriately titled Hands From Above was made by artist Chris O’Shea. Want to create your own? You might run into trouble finding such a nice billboard to use, however the programming environments he used- openFrameworks and openCV – are both freely available. His source code doesn’t seem to be available though, unfortunately. [via interactive architecture]
