Meet Alvin Sputnik, one of the few surviving humans in a world that’s well beyond any scientific predictions for sea level rise. Equipped with a special diving suit, Alvin, a creation of Australian puppeteer Tim Watts, explores the depths, encounters whales, searches for missing loved one, and learns to find happiness in a post-climate-change world. Now in its fourth year of touring the world, Watts recently stopped at New York University to introduce Alvin to an audience of kids, students, and adults; upcoming shows include Philadelphia, Cleveland, and Pinchincha, Ecuador.
