 * Demonstrates how to render grayscale noise patterns dynamically using 3D quintic noise.
 *
 * The program draws one point per pixel on the screen, calculating the color intensity of
 * each point based on a 3D quintic noise function. The noise value is influenced by the
 * pixel's 2D coordinates and animated over time.
