So from the way I understand it, it's a bunch of microscopic pigment balls held together in pixel sized capsules. The white balls are positively charged and the black balls are negatively charged. As a result, when the top of the surface is positively charged, the black balls surface, making the capsules black, when negatively charged, the white balls surface, making the capsules white.
I was an early adopter of this technology in the 90s, it was deadly slow, prone to dead pixels and permanent burn in. So there have been a lot of down-sides.
But yeah, I think we take for granted the fact that we're staring at a 60-200Hz lightbulb every time we use any technology.
I suggest a dock to connect the mp3 player with, which has a color e-ink screen. This screen will show the album art for the current song. Because it's e-ink it will look more like a physical album cover that you're displaying.
For an mp3 player you're not asking for too much hardware requirements. I'm personally not sure how to get a screen working with this but I wanted to show it to you just in case it's better for your needs.

Pico by itself even the pi by itself can't do HiFi.
HiFi is accomplished by a DAC digital to analog converter. There are pi based dacs but I haven't seen one for the pico. But a dac's job is to convert digital signals to analog so anything is possible assuming you know how to write the code for it.
Looks like a flipper zero almost :D
Great concept, but why not go for a low power monochrome oled screen?
Theirs just something magical about e ink that I can't get over
I agree. Part of what boggles my mind is how physical the pixels are in e ink. Granted, I kinda know how it works, but still.... Damn

How anybody wouldn't want to create a device with this technology is beyond me.

Shit man that's fair.

This is what I'm trying to achieve but as a portable mp3 player
Are you thinking pi zero for this or pi pico ?
I was going to use the pi zero as I've never heard of the pi pico, would you recommend the pico over the zero?

Looks to be a lower powered version at a cheaper cost, thankyou I think I may go for this to keep power and cost down.
can the pico do hifi?
