Wow.
Somehow, visualization is the most fascinating tech to me. Of course, sounds and other things are fantastic, but it all takes time to feel. For example, the sound, you have to listen to it second by second. Any fast-forwarding will result in an abnormal feeling (and we called it "distortion"). In contrast, images are just lying in front of you, and you can watch the whole film by seeing all frames (assuming it's a physical film, not something digital).
And by converting sounds and other info into images, we humans might not able to read it (you can't read a QR code by just staring at it, right? Right?), it's kind of abstract to us. But it is also concrete enough that allows us to roughly understand what's going on there. Just looking those digital dolby sound encoding in the film, it's not the changes in air pressure (something we called sound), it is the SOUND.
* Maybe, I mean maybe, because I don't know how to properly write frontend things and do data visualization, so I feel it's super cool to me. LOL

You can also "see the whole music" (score, record) like you can see films, or you can listen to individual tones or sequences like you would watch a film frame.
What I think you are talking about is the difference between the *rate-independent* #production of their #structure(s) and the rate-dependcy of their #reproduction #process.
Producing a film, music piece or SW prgram can go on for months, be interupted and resumed at will, but its reproduction, to make any sense, must be uninterrupted and at a specific rate.
The world works on #difference and #change, both structural and/or temporal.
