That’s an amazing idea and actually something like that was already developed for decades with SSTV, the analog transmitting of images via sound codes (ISS uses it to transmit photos to Ground Control). So what for us appears as a sound sequence is for a machine (i.e. SSTV decoder) an coded image sequence.

This second layer of information is thrilling in two ways: full of possibilities and dystopian. It’s what people do with this, indeed.
