What if the keyboards that we use incessantly all day would work in reality? If you could escape something by a push of a button? Delete anything by a flick of a finger? Or format your surroundings to your liking? These are the questions that Israeli designer Yossi Wallner is posing with his recent street art project around Tel Aviv. He has placed these function keys in random locations surely piquing the curiosity of those who come across them. I’ve never seen a ‘Sleep’ or ‘Wake’ key (must be a pc thing) but those make for interesting messages too. You can see more images of the project on his flickr page.
