Does anybody know any examples?
My uneducated guess is that perhaps the thing of the day now is proper voxels (not Minecraft's “voxels”) and lots of shaders on top. But then again, this endeavour doesn't really differ from just making experimental game engines.
I don't think it uses any fancy modern CPU features but this is probably the reigning champion of the 256 byte demo, and its write up[0]
I think it is this limiting factor that is partly responsible for keeping the C64 scene alive. While it is limiting, there are also still infinite possibilities of creativity. I don't personally find say, the PC demo scene as interesting because it is not really limited in any way other than size competitions. But still there you get a lot more mileage out of every opcode than on the C64.
I play piano accordion (but not particularly well). I started watching the video first and was a little troubled that the bellows appeared to be home-made, crappy looking, and not nearly as effective as they could be. Aftermarket bellows are not hard to find and are not even that expensive if you get them from China. But then I saw that he made them out of _floppy disks_ and decided that was pure genius.
This also made me realize that a computer keyboard pretty closely resembles the right hand of a chromatic button accordion, so I assume that's how it's laid out.
Anyway, he certainly plays this cobbled-together instrument far better than I'll ever play my analog accordion. There are MIDI and other "digital" accordions out there but they are either extremely expensive or limiting in terms of what you can do with them, or both. This gives me hope that one day I could possibly build my own programmable digital accordion.
This was quite straightforward to touch type with: https://twitter.com/ykarikos/status/1038145486618861573
Perhaps you were joking, and you made me smile, but there are no "analog" instruments (save perhaps analog synthesizers), because what could they be the analog of, or analogous to? They're the real thing, not an analog of something. You meant your acoustic accordion. It would be very confusing to call acoustic instruments analog, because even an electric accordion or electric guitar or digital synthesizer still uses analog electronics for amplification.
> An analog signal or analogue signal (see spelling differences) is any continuous signal representing some other quantity, i.e., analogous to another quantity. For example, in an analog audio signal, the instantaneous signal voltage varies continuously with the pressure of the sound waves.
> In contrast, a digital signal represents the original time-varying quantity as a sampled sequence of quantized values which imposes some bandwidth and dynamic range constraints on the representation.
> Analog devices are a combination of both analog machine and analog media
So, in common scientific use, this is fine. You are speaking of accordion analog, not analog accordion.
> In signal processing, a signal is a function that conveys information about a phenomenon.[1] Any quantity that can vary over space or time can be used as a signal to share messages between observers.
> In nature, signals can be actions done by an organism to alert other organisms, ranging from the release of plant chemicals to warn nearby plants of a predator, to sounds or motions made by animals to alert other animals of food.
Sounds are also signals. And using "analog" with accordion is not strict technical term, it's layman's term for "not digital". According to your usage, Commodordion is not digital, because it emits sounds, not numbers.
Tu quoque, ad hominem, and equivocation. "Signal" has multiple distinct meanings. You are conflating homonyms in equivocation, as well as attacking me personally while arguing, "you too!" Not all signal, by the definition you're conflating, is sound (such as semaphore, gesture, facial expression and even pheromonal response), and by the same vague definition, not all sound is signal (such as Berkeley's tree falling), not unless it is communication.
Context and semantics matter here. If we define sound as signal and vice versa, then there is no literal distinction between acoustic sound and analog signal, creating ambiguity and confusion. In the context of audio and sound, and from your own citation:
> in an analog audio signal, the instantaneous voltage of the signal varies continuously with the sound pressure... The term analog signal usually refers to electrical signals
A sound is also a a long, wide body of water that connects two other bodies of water, but it would be absurd and equivocating identical words of different meanings to claim that acoustic sound is also a body of water.

Cool stuff
I haven't done a proper writeup yet and there's no retro-computing involved, but perhaps folks will be also be interested in a demo of my homemade accordion. (MIDI controller, technically; sound generation is on a laptop.)
Is the source code available? As a C#/D player, I find the relationships between the rows unfriendly, and miss the bottom two buttons of the row. Plus I'd love to have real accordion sound samples, and maybe MIDI output...
(ooo, plus I guess if you only wanted two rows of right hand notes, then you could have two rows of bass buttons, just like a real box only with a lot more chords available...)
But then again practicality isn't a high priority for this thing.
Linus is one of the demoscene's experts on fastloading too, so he may not use the default loader!
But TBH when I saw the thread I was expecting something a little more like Keith Cary's Commodium (a mandolin made from a metal bedpan)...

Now I want to figure out how to build a guitarch-linux.
It heralds the coming of the Spectrophone and the Amiguitar.
This is such an amazing display of talents, it requires and analysis video of its own to go over the geekery, the music, the time and effort, the creativity, the whys and hows. I was speechless and awed throughout the video and reading about the project. I feel so lucky to have seen this!
Happiness.
I was not informed about its history, so I checked, and discovered that it means "satiated" - so the current use of 'sad' comes from the idea of the discomfort that being burdened by too much nourishment brings.
You must mean that the project is very "satiating". Good: surely it can fill us with a most fulfilling nourishment. But I would have used the most unambiguous term.
I believe there is a certain element of sadness in that. However it's hopeful that he will continue experimenting with the lessons learned, so I wouldn't describe it as sad.
