       | "All rule lookups and most of the collission detections are
       | calculated on the GPU."

       | the performance he has managed to gain ..

       | I've been interested in continuous automata for a good while! I

       | Scott", but I actually mean the whole realm of solving various
       | types of equations (in feedback of course) on continuous-valued
       | fields. My software of choice for that is gollygang/Ready (where
       | some of my experiments are available to play with in the release)
       | and also Houdini, to use the resulting simulation data in
       | whatever way one creatively desires!

       | Here's one from my channel:

         | But it's mostly always seemed like a software toy
