A mobile is a type of kinetic sculpture consisting of an ensemble of balanced parts that hang freely and move independently or as a whole when influenced by air currents or touch. Typically made of wire and colorful metal shapes, mobiles are designed to create dynamic visual effects through their motion.

Offset lithography is a printing technique where the inked image is first transferred (offset) from a plate to a rubber blanket and then to the printing surface. This method combines the lithographic process, which relies on the repulsion of water and oil, to keep non-printing areas ink-free by attracting a water-based film. Offset lithography was originally developed to reduce costs in reproducing artwork and is widely used for high-volume printing due to its efficiency and ability to produce sharp, consistent images.
