That is a nice Grasshopper project. This application of Plateau's laws is limited to an idealised and very regular geometric situation, though. More general problems can be solved with the Surface Evolver, which, like Frei Otto's form finding experiments, can evolve membranes (starting from a certain initial configuration and geometric constraints) under gravity and particular bending energies.

The Willmore energy is a neat way to get smooth or "fair" bubble-like surfaces. https://en.wikipedia.org/wiki/Willmore_energy
