The form arises from a shape discovered by Celso Costa of Brazil in 1984. That shape is related to energy-minimizing surfaces that arise naturally in the physics of soap bubbles; see photo of a soap bubble demonstration in sub-freezing conditions by Matthias Weber. Costa’s discovery marked the start of a new era in the investigation of these surfaces, technically called minimal surfaces.


This project in stone was inspired by a similar construction, Invisible Handshake I, created in 1999 at a snow sculpture competition; photo below.
