An interior renovation project with a multi-floor atrium called for large-scale, space-defining artwork. Our team wanted to evoke the idea of falling leaves with organic shapes cut from acrylic sheets and suspended from ceiling-anchored cables. But our imaginations ran in too many directions to sketch or model manually. Our solution was a parametrically driven script, with all the variables we wanted to explore built in. The tool we built instantaneously generated new iterations of the geometry as we fine-tuned the parameters towards a final design.
