Nancy Baker Cahill’s multifaceted augmented reality (AR) public art project, Mushroom Cloud, is a project focused on accountability; one that values sharing and conserving resources, and strengthening networked systems through participation, communication, and advocacy. The work speaks to rising waters, to viewers raising their gaze to witness the sky-covering mycelial network, and to collectively rising to the opportunity to combat the climate crisis through distributed support, mutual accountability, and environmental stewardship. Mushroom Cloud acknowledges the imminence of this cataclysmic crisis while offering hope that through cooperative and constructive action, a vibrant and vital future is still possible.
