Another relevant work of Barney’s is the installation Sin título (Untitled), with which she participated in the collective exhibition Aspectos de lo tridimensional (Aspects of the Three-Dimensional) at La Tertulia Museum of Modern Art in Cali, curated by Miguel Gonzalez whose objective was to show how the manner of approaching objects and sculpture had been transformed in Colombian art during the second half of the twentieth century. In Barney's enigmatic work, the viewer was confronted with three metal structures covered with rustic canvas and could climb the stairs in each of them to discover their contents. One contained an acrylic box, in turn filled with small boxes with the seeds of tropical trees; in another hung a gallon of chlorophyll-green paint leaking, while the third was filled with chicken eggshells.
