The theme I would suggest is Changing the World One Step at a Time: What would you change about our world? It would be kind of a mixture of Genie in a Bottle: Three Wishes and Repurposing: The Ultimate in Creativity and Recycling. People could pick a variety of things, such as: health, time, language, peace, etc. This theme would be a way for people to illustrate the world they would like to live in and give the audience ideas on how we can better this world.
