*Prototypes and Provocations* surveys Rael San Fratello’s experiments at the intersection of architecture, technology, politics, and sustainability. Projects range from the pink *Teeter-Totter Wall* installed at the U.S.-Mexico border to structures 3D printed from earth. Using materials including soil, grape skins, coffee grounds, sawdust, and wildfire ash, the studio explores new ways of building while questioning architecture’s relationship to borders, power, and community.
