Famous conceptual artists focus on the idea behind their work rather than the final product. One notable figure is Marcel Duchamp, who challenged traditional art by presenting everyday objects, like a urinal, as art. His work encouraged viewers to think about the meaning and context of art itself. Another influential artist is Sol LeWitt, known for his wall drawings and instructions for creating art. He believed that the concept of the artwork was more important than its execution. This approach has inspired many contemporary artists to prioritize ideas over aesthetics, reshaping the art world in significant ways.
