Nongeometric shape armor
The vehicles make with the geometric shape armor aren't soo look. A good example to show this is crossout. Crossout is a game you make a post apocalypse car using armor of scrap, like cap of fenders. It's like a 3D Tetris, with thematic pieces in "L" shape for example. So imagine instead a glass maked with plates to create a bridge, a "U" shape glass, or a plate with futuristic details, for example.
