Surrealism is a cultural movement that began in the early 1920s, and is best known for the visual artworks and writings of the group members.
Surrealist works feature the element of surprise, unexpected juxtapositions and non sequitur; however, many Surrealist artists and writers regard their work as an expression of the philosophical movement first and foremost, with the works being an artifact. Leader André Breton was explicit in his assertion that Surrealism was above all a revolutionary movement.
I like this style for getting free imagination. Forms and qualities become different than we have ever thought! Isn't it magical?
