Combined an RBD sim with mesh generation and a lite pop sim in this Houdini experiment.
Played around with a few more Karma render features, as well. Their transparent depth and thin surface features make for some interesting surfaces.
The first half is built from a fairly simple geo duplication loop and pop-sim.
An early flipbook of the RBD sim with fluctuating rest lengths. The electric arcs are also based on this constraint geo.
Tried a different camera setup and animation for a smoother loop. Felt like the view got a bit too tight and limited though.
