Okay, I have posted a preliminary cross-language implementation for `random` / `randomSeed`, here:

> I have developed a set of demo sketches that implement simple cross-language random numbers. The goal is to make it easy to adapt a sketch between Processing (Java), p5.js (JavaScript), or Processing.py (Python) such that passing the same random seed to each version will generate the same “random” playback from a generative artwork. This is currently not possible using the core modes / libraries, as they each use different underlying systems for generating random numbers. One solution is to im…

There is no `noise` / `noiseSeed` included yet, but that might be built on top of it.
