Imagine you’re a tourist. Innocently taking pictures of everything you find worthy and discovering later on, that your pictures aren’t really showing what you first saw through your objective.
Someone could be messing with tourist photos using the Image Fulgurator. It uses a flash triggered sensor, projecting a message of your choice onto a targeted surface at the exact time when a picture is taken. Besides being subversive enough to derange, I truly wonder what could be the point of holding (and using) such a device. Can you imagine?
