Circuit art combines engineering and beauty by using electrical components like lights, wires, and circuits in artistic creations. Examples include holiday light displays on houses and trees. The document encourages readers to express their creativity by designing their own piece of circuit art, combining materials that conduct or insulate electricity into things like greeting cards, wall art, or desk displays. It provides examples of existing circuit art and guidelines for creating your own, such as sketching a design, attaching an LED and battery correctly, and testing connections to bring the circuit to life integrated into your artwork.
