Decorative patterns have existed since the dawn of civilization, since humans began using art to convey emotion, instill mood, and shape atmosphere. From the pyramids of Ancient Egypt to the city skyscrapers of the 21st century, we incorporate patterns to design spaces with deep significance, strong feelings, and intricate beauty. Different styles or patterns — through their repetitive shapes, curves, and angles — can make us feel productive, relaxed, creative, or energetic.
