/** 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.
