Nota Anna is the result of decades of research in choreography and teaching of movement for adults and children, plus theoretical studies in the visual arts, video art, anatomy, physiology, neurology, movement analysis. This search has two stages: first the generation of movement through computer (1973 76) which focused on video dance area and the second that expanded the sphere of dance to any form of corporal expression. Nota Anna intended to any type of motion like dance, everyday movements, sport and even other animals.

Cambiantes (1976) is one of three computer dances for video, created by Analivia Cordeiro. It is a research on interaction between the human movement and video, using computer and programmed in Fortran IV language. Cambiantes is a high contrast, black&white video that redesigns the rectangular shape of the video monitor (or display) through geometric forms, as triangles, that penetrates the scene. Inside this space, the dancers move based on right angles and diagonals performed by the body. The sound is an electronic music by the Brazilian composer Raul do Valle.
