Thanks! Yes, it does update quickly, and ghosting is still an issue, though I think there’s room for improvement on the OS/software side. I gave a talk at the Linux App Summit earlier this year where I shared some ideas for how this could work.

I think, if you look at Boox and how they have display options and config for each app, you could do this for X11 quite easily. Especially a custom backend video driver which flattens to greyscale, and distinguishes change on a per app basis.

An incredibly hacky thing, is that (as an example) Sawfish is an immensely extensible window manager. You can literally drop in lisp code linking actions by tagging on window names, application names, and so on.

So you could actually extend sawfish quite easily, and then do what Boox is doing. Change per-window methods of refresh, by interfacing with the backend video driver in X11, and so on.

I think a lot of people who don't use Linux, would "put up" with Linux if there was a way to use a framework with a display. So I think, strongly think, that the display of course and your work of course must be done, but that it relies very strongly on slapping together a more holistic environment.

Just thoughts. And good luck with this.

Thank you for your thoughts and support. I agree, doing this in X11 is definitely doable. I’ve seen others achieve similar results by running a daemon that listens for damage regions. I hadn’t considered using a custom backend video driver; that’s something I’ll be looking into.

My focus has mostly been on Wayland, but possibly prototyping in X11 could be a starting point. Some people I've met are interested in using computer vision techniques at the hardware level, or making a camera rig.

What excites me most is getting this into people’s hands, seeing what they create with it, and working together to improve it and explore new use cases. One use case that I learned about recently:

Heh, neat use re: tank + fish!
