Festival of arts that has earned the title 'the most abstract in the world' explores the possibilities provided by dots (puntos) and lines (rayas) in the worlds of science, art and thought. It includes 'pyrformances', workshops, conferences, and an official competition on the central theme of the festival where video and CGI artists from around the world participate. A retrospective looks at the work of Larry Cuba, who pioneered the use of computers in animated art with his first item produced in 1974, entitled 'Larry Cuba and other classics'.
