Vales developed a prosthesis called harvest to facilitate harvesting crops on water and hillside. This device records the movements and translates them into artistic expressions the Vales enjoy watching in public. The outside world is interested in monetizing the prosthesis to measure production and increase efficiencies. The Vales don’t want commerce to interfere with their art.
There exists a movement protesting the commercialization of the device since it’s an art basis. The two protest graphics represent graffiti around Rilao that defends the pro and con.
