Exhibit: How Many Like Me?

Enter the colour of your hair, the colour of your eyes, how you fold your arms, etc.  The computer has collected this data from many previous visitors and will tell you how many people have the same characteristics as you.  It is surprising how few there are.  When you have answered the eight questions about yourself, the computer compares your answers with all those it has accumulated this year from previous visitors, usually tens of thousands.  The results are displayed in a cumulative way.  The total number of combinations of the eight traits is about three thousand.  You may find that there are only a handful of people with just the same set of traits as you.
