You can probably buy an e ink display on Alibaba for less than $100 if you negotiate enough.

This one is 12.5" [0] which might be large enough for a lot of use cases. If not I suppose multiple ones can be stacked right next to each other.

It seems like the actual display he mentions in the article is available on alibaba as well, though it is $1500: https://www.alibaba.com/product-detail/Largest-E-ink-Display...

To get to that size stacking 3 of them on top of each other probably wouldn't look so bad, it'd be like having 3 <hr> tags on the page.

Hell, since we're talking wall-art here, just embrace the separated look and call it a triptych.

The spec sheet on that link says '2x FPC interface', what does that mean? When I google 'fpc to hdmi' I get a bunch of generic hdmi cables. Is 'FPC' just a form factor to transfer an hdmi signal? More to the point, how would I hook up a display like this to an RPi, and how would I hook up 3 to anything without using a GPU with 3 outputs?
