Abstract
A water display is described having different layers that each include a geometric shape. Water is provided to and drained from the display to vary the height of the water between the layers of the display. As the water height increases or decreases from one layer to another, pools of water assuming the geometric shapes formed in a given layer appear. The geometric shapes formed in a given layer appear. The geometric pools of water transform shapes as the water is raised or lowered.
