Invited by Swarovski, Ma Yansong designed and produced a large-scale installation work called "Moon Realm" for the Digital Crystal exhibition. The exhibition was held during the Beijing Design Week from September 28 to October 3, 2013.

This work, with irregular black polyhedrons as the motif, is shaped like rocks, extending from the outdoors to the indoors, evolving from an exhibition space to an artwork. Walking in the black, winding space, the entire exhibition is like a surreal journey through time and space, with each artwork placed inside a mountain and appearing in the space along the way. After the visitors have visited the entire route, they will climb the stairs at the end of the journey and come to the sky above the entire exhibition space, where a glowing digital moon is waiting for them, hanging above a silhouette-like mountain. The surface of the "Moon Realm" changes subtly over time, from digital images to natural reality, allowing people to stay in the eternal moment from the past to the future.

Swarovski's "Digital Crystal" exhibition aims to explore the concept of memory in the digital age. The exhibition features specially created works by five emerging Asian designers, Ma Yansong, Liu Feng, Li Naihan, Shi Jianmin, and Song Tao, as well as works from Western designers Arik Levy, Maarten Baas, Random International, Yves Béhar, and Ron Arad. Each designer interprets how memory is perceived in the digital age in a different way, and explores the ever-changing relationship between humans and things, environment, and time.
