One of the most immersive and captivating digital displays I've ever experienced. The Rock where People Gather is reproduced in a virtual three-dimensional space. ..Water is simulated to fall onto the rock, and the flow of the water draws the shape of the waterfall. ..When a person stands on the rock or touches the waterfall, they too become like a rock that changes the flow of water. ..The flow of water continues to transform in real time due to the interaction of people. Previous visual states can never be replicated, and will never reoccur.
