Zou Luyang completes this installation by adopting the principles of optics through precise calculations, modelling, and trial and error. Using three-dimensional printing technology, Zou creates a sphere of calculated and accurate dimensions encased in plaster and gives a textural and visual effect shaped like the moon's concave and convex surface by moulding the surface texture. Using controlled lighting, specular reflections and changing shadows on the sphere, Zou creates an artificial view of the moon's cycle of waxing and waning. It invites people to escape from their head-down immersion in the virtual world for a few moments and to reconnect emotionally with their past lifestyle of living close to nature by viewing the artificial lunar cycle. The realistic visual texture of this lunar surface, the soft moon-like brightness of the light and the soothing rhythm of the changing light and shadow are the contemplative experiences with warmth and empathy that Zou expects to provide the viewer.
