In Un Bárbaro en las Sierras (A Barbarian in the Hills)(2015) Cambre experimented on an unstretched canvas with a series of squares and rectangles in
several colors framed by bright yellow lines; he translated the arrangement into blue on another square canvas, then copied the same shapes, but in different positions and in green, for an
outdoor mural in Buenos Aires, before finally rearranging them again for a brown canvas in yet another configuration.
