Hyberbolic Surfaces was created as part of the 'Methodology' workshop run by Mette Ramsgaard Thomsen in the spring/summer semester 2017 at CITAstudio. The task was to replicate an experiment and we chose the work of Jenny Sabin of Cornell University, specifically her Branching Morphogenesis project. Jenny Sabin's work explores how insights from biology and mathematics can be modelled and fabricated. We created different surface variations in joined elastic band cells using different numbers of neighbouring cells. We found that using 5 cells would create a convex/concave dome, 6 cells would make a flat surface and 7 cells would create a hyperbolic surface. A hyperbolic surface is a non-euclidean surface made up of saddle-shaped curves, seen in nature in coral reefs.
