You know one thing I thing is interesting is simply having people listen to their varying pitch sensitivities as they simply change the shape of their own pinnae.  They can do this simply with their fingers and some gentle bending.  It's typically high frequency reflection, but it is remarkable.  There's lots of other stuff to fiddle with if you want to call it an exhibit.

The tubes can be oriented in different directions and can imitate the side and front facing ears of an owl.  It presents a 'different' perspective for the participant.
