There used to be. It was there when my class took a field trip in 1994. It didn't display the words visually, just played them from all directions as though you were walking through a crowd of people hissing/hurling racism at you. It also wasn't a moving walkway, so you could just stand in there. I know it was meant to be serious, but we 6th-graders thought it was hilarious.
No and no
If there is, I missed it.
