Aquarium windows, not mere transparent dividers.
Their design harbors deep aesthetic sense.
Proportion-wise,
the length, width, height settings
suit human visual comfort.
Shape-wise,
either sleek or edged.
All blend with the space.
The right proportion and shape are space's accents,
broadening and layering the view,
animating the area via the window,
displaying space's harmonious elegance.
