Reynivellir is a representation of the transit that is generated when approaching the art work, described with visual games that can well be evoked by the same brain when witnessing the impossible figures of Jose María Yturralde. Reynivellir is also a beach in a country that is a musical sonnet, and this is so because the mental image does not always connect the articulated parts of a sensation, it is systematic, but aleatory, and it is from these notions of the field of observation, that it approaches and moves away from understanding, linking and unlinking forms, movements, sounds, sensations and knowledge.
