Other exhibits have more of a hands-on approach and invite participation from the visitors.
This year's workshop activity is crane origami, with a twist! You write "a change that you want to see" on that piece of paper, fold it into a crane, and replace one of the cranes on the panel. The cranes on the panel will also have something written inside, and you get to open them up and read those wishes. A pretty interesting way of communication/interaction.
