I wanted an e-ink photo frame. Because these are so expensive, I’ve been thinking about hacking up a rolling box frame where high quality photos can be made into a “roll” and have motors on the top and bottom to roll up to see the next pictures. Perhaps a little diffuseD backlight would even make the printed photo pop a little. Something like this. https://m.made-in-china.com/product/Outdoor-Custom-City-Adve...

Don’t know what it is called in English properly to search for such things..
