+ * Demonstrates how to render a dynamic grid of points where the color of each point
+ * is determined using a hash-based noise generation method.
+ *
+ * The application dynamically updates the visual output by calculating a 3D hash
+ * value for each point in the grid, based on the current time and the point's coordinates.
+ * The hash value is then used to determine the grayscale color intensity of each point.
