If you are retarded and need to wear a helmet around to keep that noggin of yours safe, you might as well make it entertaining for others around you. I guess. I’m not really sure what other uses there are for this except perhaps as a way for construction workers to pass time on their lunch breaks. In any case, this is a hard hat with an LED display on the front that plays Pong and displays messages for some reason. Of course! [Instructables]
