Our ChemMystery exhibit uses a hidden coin-histogram setup for
visitors to vote for the one (or more) suspects they think committed
the crime. You cast your vote on one side of an 8' x 8' panel by
inserting a penny into the slot corresponding to your favorite
suspect; then you get to see the histogram of everyone's votes when
you walk around the other side of the panel on your way out of the
exhibit.
