A demo of the Bad Apple music video played back at 60 FPS on an e-ink display, up from 2.4 FPS in an earlier attempt. It is part of the effort behind the open source Modos e-ink monitor.
HN cites it as the demonstration that e-ink can do low-latency, video-rate refresh with an open hardware controller.

I'm skeptical not of the claims but of the usability long-term, tablets like the BOOX Tab Ultra C look great but they commit to violating the GPL rather than giving users a chance to mess with the internals. I've been loosely following the works of Wenting Zhang and their modos.tech which have a fully open hardware controller that can run at 60FPS[1] with 1bit BW and still seem pretty decent latency-wise with grayscale on[2]. Sadly most of their public activity nowadays seem to be on building a DIY MILC camera so don't know if we're ever going to see a full version of this. 1. this video 2. [LINK]
I feel like e-ink displays/EPDs are widely used, but underexplored, by major manufacturers at least. The person behind the Modos project already linked by someone else has put a lot of effort into pushing EPDs to their limits and put together the best technical documentation for EPDs that I know of: [LINK] EDIT: Here's an older demo of theirs: this video
They have a video where they have an eInk display show video at 60 Hz. In contrast to a previous video, where the display was running at 2.4 Hz and the video then sped up by 10x, this is not sped up. What kind of black magic is this? this video
Demo of the music video "Bad Apple" being played on this monitor (or at least an iteration of it): this video
