The photo below popped up on our sidebar flickr browser.  It is an image of the Ampelmann:

(German: little traffic light man) is the symbolic person shown on traffic lights at pedestrian crossings in the former German Democratic Republic (GDR – East Germany). The red Ampelmännchen extends his arms to signal “stop,” and the green Ampelmännchen confidently strides ahead to signal “go.”  – via Wikipedia
