Having fun at Zao is one of our values. We’ve put limited animated flourishes throughout our site to communicate our love of levity. We also recognize that onscreen movement is not fun or possible for everyone. We've turned off all our animations for you per your browser's request to limit motion. That said, we don't want you to miss out on the party.
