By Natalie Willis. Forward, onward, digging upward in the sand, together. The 2018 “Double Dutch,” the 7th in the series of paired exhibitions, brings us questions on the future, on climate change, on what it means to govern a chain of 700 islands, and on what it means to lose an island’s culture from lack of infrastructure and intervention. “Digging Upward in the Sand” (2018) by the Plastico Fantastico Collective, stirs up these queries, worries, and troubling presents for us.
