Naziha Mestaoui's light installation "One heart, One tree" was inspired by her experiences traveling among aboriginal peoples in the Amazon, India, and Oman. These include the Huni Kui and Ashaninka in Peru and Brazil. The project was crowdsourced through Kickstarter, and developed over a four-year period. An early version, entitled "One Beat One Tree", was presented at the United Nations Conference on Sustainable Development (Rio+20) in 2012.
