/** This function creates an interactive graphical application that displays a dynamic visual composition
 * of rectangles, which are generated and manipulated based on time and random parameters. The application
 * follows these steps:
 *
 * 1. Initializes a random generator seeded with the elapsed seconds since the start of the program.
 * 2. Creates a sequence of rectangles using the `uniformSub` function to generate random sub-rectangles
 *    within the bounding rectangle of the canvas.
 * 3. Distributes the generated rectangles horizontally within the canvas using the `distributeHorizontally` method.
 * 4. Aligns the rectangles vertically according to their position in relation to the bounding rectangle
 *    and a dynamic anchor point derived from the cosine of elapsed time.
 * 5. Renders the rectangles on the canvas in the output window.
