An "Art Car" is a vehicle that has been transformed into a piece of art through creative modifications and decorations. Artists often use paint, sculptures, and various materials to enhance the car's appearance, turning it into a mobile canvas. These cars can be seen at festivals, parades, and art shows, showcasing the intersection of art and transportation. The concept of Art Cars gained popularity in the 1980s, particularly at events like the Burning Man festival. They serve as a form of self-expression and community engagement, inviting viewers to appreciate art in an unconventional format.
