You could order the presentation of a set of images by some distance metric :) - naively: Levenshtein - better: real world edit time based on a model of the display : probably dominated by XY travel distance

Oh I kinda love the idea of drawing the next one based on the pixel diff! Would be fun to game that queue.

Another idea: have the cubes point an edge straight forward (instead of a face). Then if each cube has two adjacent dark sides and two adjacent light sides, one could setup two ‘simultaneous’ images: one viewed from the left at 45° and another viewed from the right. (Each pixel would have four possibilities.)

Earlier quoted context omitted.

I think I might put this in my friend's coffee shop but I'll restrict access to people in the coffee shop. Not going to let the internet get a hold of that. In addition to the user-controlled modes I also have ambient modes. My favorite is a clock that struggles to draw the current time because it takes too long

You gotta do the classic bouncing logo from The Office.

Genius. I'll do this when I install it in my Zoom background and take it off the internet

Awesome project! I built a somewhat similar 30-pixel display: https://www.chrisfenton.com/the-pixelweaver/

Mine was entirely mechanical (driven by punch cards and a hand-crank), and changed all of the pixels in parallel, but a lot of the mechanism development looked extremely familiar to me.

Speaking of "alternatives to e-ink for a zero-power-use-when-not-updating dot-matrix display"...

Has there ever been designed a "display" that is just a thermal printer hidden in one end of a box, and a take-up spool + tensioning spring hidden on the other end, such that the "display" is then a continuous thermal paper "scroll" stretched across the box behind [UV-protective!] glass, that can be "refreshed" by printing a new full-width image to the thermal printer?

This used to exist! I remember a video about this large analog billboard in Amsterdam (?). Unfortunately I can't find the video. Will edit if I do (or anybody else finds it first).

Perhaps you are thinking of Daniel Rozin's "Wooden Mirror" (1999)?

Allow me to correct you: Some fax machines use thermal paper so your display can be at least 8.5".
