The ornamental design for a "water wall for displaying dynamically changing water patterns," as shown.
FIG. 1 is a side perspective view of a water wall showing my new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a top view thereof; and,
FIG. 4 is a left side elevational view thereof, the right side elevational view being identical.
The rear of the water wall is flat and unornamented. The central front element of the water wall shown in FIG. 1 and FIG. 2 is a translucent material. The front surface of this element is flat. A grid of concave depressions in the rear of this element shows through the element and is visible from the front of the water wall. In FIG. 1 and FIG. 2 the visible pattern is shown at the diagonal corners of the element for convenience of illustration, it being understood that the grid of concave depressions is continuous over the entire rear of the front element and that the pattern shown on the front surface extends over the entire front surface of the element.
