For 'Ars Electronica 2020: in Keplers Garden' I joined the Amsterdam Garden at Waag's Planet B with an experimental online performative lecture. While I shared my thoughts around perceiving clothing and housing as external skeletons, combining the organic and the mineral, creating an inside and an outside by the formation of a shell, and sounds of calcification, Marloes Bistervels was growing mineral-architectures LIVE at the Self-Organizing Matter group at AMOLF.
