I wrote this a LONG while back. At the time, I was fresh out of college and my first job included a lot of reverse engineering communication protocols to make machines work together for automation purposes. I will personally testify to how useful it was to see visual patterns to aid in this. The single biggest benefit was seeing that one particular protocol switched endianness WITHIN a specific packet.

I am guessing that the HN audience would be / should be interested in that distinction. Mathematically speaking, chaos is an extreme sensitivity to initial conditions, and is very much still in line with deterministic systems. The resulting output, while seemingly random (since there is no easily identifiable pattern), is mathematically and conceptually different from actual randomness.
