The Art Of The Design

Over the years I noticed the use of geometric shapes as art in film and I've always been curious about their purpose within the story. What is its intended message. Whether it's a closeup of the outside of a build's architectural design or a bird's-eye view of a winding staircase, how do those images progress the story being told? Are they creative fillers, dynamic visuals, or conveyance of subtext of some sort?
