Here we have a young participant of the second Belfast Carnival (no I don't know what she is dressed as) playing on a street installation. Stepping on the squares produces a note (a bit like the chime of a bell) so if you are any way musical you can produce a fairly basic tune. They actually sound a bit like wind chimes. Anyway, as you can see our young friend is having fun - a bit like playing hopscotch on a xylophone.
