/**
 * 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.
