Here's a pedestrian safety idea I can get behind. Placing LOOK signs on the street at crosswalks wont be a panacea for ending vehicle vs. pedestrian accidents, but it does encourage responsibility on the part of pedestrians. Making them feel safer, as most pedestrian safety efforts do nowadays, just seems to make people more careless.
One thing that might make it more effective would be to have an image of a hand pointing a finger on both sides of the word, pointing left and right. That might better remind people to look both ways before crossing the street.
