This document describes a public media art installation called "Moon Rising from Sea" being designed for the center square of a new living and leisure area in Taicang, China. The installation consists of a 10x10m base with wall reliefs and an 8m tall structure resembling a sail with the moon rising from waves. Projectors will display images, animations and videos on the sail's surface in the evenings. The design process involved workshops to inspire designs from traditional arts. The installation will allow the public to contribute photos from social media for an interactive photo show, connecting people in Taicang to those overseas and reinstating Taicang's historical role as a port.
