The two pieces here are Postcommodity's Repellent Fence and Oscar Murillo's collective conscience.
The Repellent Fence is more than this one balloon. It was a two mile long land-art installation of 26 tethered balloons that are ten feet in diameter and floated 100 feet above the ground. The balloons floated above Douglas, Arizona and Aqua Prieta, Sonora. The balloons, themselves, are based on an ineffective bird repellent. The project was a collaborative project among a variety of individuals and organizations and was a symbolic attempt to suture together the people of this continent.
Collective conscience continues Morillo's exploration of labor in our capitalist world. He uses Mateos, effigies used in New Year's celebrations in Columbia. He has employed these effigies as symbols of the proletariat. These workers, when you look close, are partly dismembered and indeed, digested, by the system that both consumes them and in which they are consumers.
