Imagine No Sight
Imagine No Sight is a guerrilla advertising concept for the American Foundation for the Blind. The idea is to have seeing pedestrians try to walk a block in the shoes of a blind person. While the pedestrian would be walking the block, volunteers from the foundation would interact with them. Some volunteers would bump into the person, some would make rude remarks about them not being able to see or walk straight, and others would make it hard for them to reach the end of the block.
Depending on the location, the stickers and text would be placed on ramps leading to the sidewalk, and others would just have a poster explaining what to do. Ideally, this would happen one block at a time for the greatest effect. The last piece would be a small card that would be handed to every pedestrian who participated.
