Object assembly is an art technique that involves creating three-dimensional artworks by assembling found objects and materials. The technique emerged in the early 20th century, and was used by artists such as Pablo Picasso and Marcel Duchamp as a way to challenge traditional notions of art and representation.

Object assembly involves taking ordinary objects and placing them in new and unexpected contexts, often creating complex and surrealistic images. The technique emphasizes the importance of texture, color, and form, and often involves the use of unconventional materials and techniques.

Object assembly has been used in a wide range of artistic contexts, from sculpture and installation art to fashion design and product design. It has been used to explore a range of themes, from identity and culture to the relationship between the individual and the environment.

Today, object assembly continues to be used by artists and designers around the world to create innovative and visually striking works. The technique has had a significant influence on contemporary art and design, and continues to be celebrated for its ability to challenge our assumptions about the nature of reality and representation.
