Figure–ground (perception)from wiki:
Figure–ground organization is a type of perceptual grouping which is a vital necessity for recognizing objects through vision. In Gestalt psychology it is known as identifying a figure from the background. For example, you see words on a printed paper as the "figure" and the white sheet as the "background".
(Figure shapes are also known as positive shapes while the shapes of the ground are negative shapes)

from wiki http://en.wikipedia.org/wiki/Octavio_Ocampo
Octavio Ocampo was born on 28 February 1943 in Celaya, Guanajuato, Mexico. He grew up in a family of designers, and studied art from early childhood. At art school, Ocampo constructed papier mache figures for floats, altars, and ornaments that were used during carnival parades and other festivals. In high school, Ocampo painted murals for the Preparatory School and the City Hall of Celaya. Ruth Rivera, daughter of artist and muralist Diego Rivera, and Maria Luisa Mendoza encouraged him to attend the School of Painting and Sculpture of the National Fine Art Institute.
The talents of Octavio Ocampo are not limited to painting and sculpture, but also extended to acting and dancing. At the Art Institute of San Francisco, he studied all these disciplines and pursued both a film and theater career. In 1976, he began to devote himself solely to painting and sculpture. He now works primarily in the metamorphic style – using a technique of superimposing and juxtaposing realistic and figurative details within the images that he creates.
