A sassy and silly reader of this blog sent along this link yesterday -- thanks Lloyd61. The Germans are very inventive people. First the uber fun-driving Volkswagon (particularly the extra-fun, sportiest, most affordable convertible on the market -- the Cabrio -- may they resurrect it again one day), and now this important contribution to the world.
Besides being a little icky, this item really is public service, entertainment, and political activism rolled up into one. It warns people not to step into excrement, is generally funny, and it involves people in the political process. Only the Germans could have engineered something so intricate.
