A series of site specific sculptures commissioned by Future City for a new south Cambridge housing development. Each sculpture is fabricated from a block of Portland stone that has been cut in half, scooped out and filled with organic materials before being re-assembled and re-sealed. Holes drilled into each piece connect the external surface with the interior organic-packed cavity to create an impregnable habitat for insects. Small forms were initially handmade by the artists, referencing natural objects that function as habitat for invertebrates: the shell of single cell amoeba; a case built by a caddisfly; a cut timber log. The handmade forms were then 3D scanned, amplified and rendered in stone by a digital stonemason using a Kuka robot.
