Drip painting is a form of abstract art in which paint is dripped or poured onto the canvas. This style of action painting was experimented with in the first half of the twentieth century by such artists as Francis Picabia, André Masson and Max Ernst, who employed drip painting in his works The Bewildered Planet, and Young Man Intrigued by the Flight of a Non-Euclidean Fly (1942). Ernst used the novel means of painting Lissajous figures by swinging a punctured bucket of paint over a horizontal canvas.
