árbol-antena is an intervention at bosquemuseo – located on top of the Calan hill, where an old astronomical observatory coexists with degradated native flora–. The project explore the interconnection and energetic communication among vegetal species, minerals, energy fields and antennas; being all them inhabitants of this place. Built from a dry trunk (agave flower) found on site, which was replanted and intervened with a copper coil, the piece becomes an artifact that intercepts and transmits signals and electromagnetic waves captured on site, being activated and feed by the sun and its energy. This tree-antenna also plays the role of a "gnomon" or solar marker which aligns itself according to solar and andean coordinates of calendrical-ritual importance, thus projecting the shadow on the ground according to alignments traced on it.
