>What does an "analog virtual thing" look like?

The image of an apple, stored as an analog signal on a magnetic tape.

>A "digital physical thing" is just a physical thing (disc) with digital things encoded on it.

Correct, a digital physical thing stores digital virtual things, and an analog physical thing stores analog virtual things.

> image of an apple, stored as an analog signal on a magnetic tape

If I am following along...

analog virtual: representation of apple on photographic film digital physical: disc with film.mkv

Given the two remaining combinations:

analog physical: unexposed photographic film? digital virtual: binary-encoded data (film.mkv)?

Anything beyond this and it becomes a philosophical or metaphysical discussion though.

Another example of Analog Virtual is Hokusai's The Great Wave (and similar prints). I recently watched David Bull's videos about his recreation of it [0] and it was fascinating to hear him tell about how even the "original" prints were made from slightly different woodblocks made in the same workshop.

>digital virtual: binary-encoded data

Arguably the raw binary data still has a physical aspect, because it hasn't been interpreted yet (other than a reordering by the file system). The virtual thing is what the data ultimately represents.

Another subtlety is that a drawing on a page would be an analog representation of the thing, but if the drawing has the shape 右 and the page is placed between two doors, there would be a virtual idea encoded digitally as well.
