When I was in Stuttgart I made a point of visiting the one they have in the Rathaus. It's an interesting mechanical design, but definitely assumes some personal responsibility on the part of the user. Keep your hands to yourself as you go around the top and bottom...

Actually they have two in the Rathaus, a modern one in the front and an older one towards the back. One of the university buildings has one too.
