It reminds me of this

In Christopher Nolan's "Interstellar," the "Interstellar library" refers to the tesseract, a 5-dimensional space within a black hole, visualized as a bookshelf. This structure is not a physical library but rather a construct created by future humans, allowing Cooper to interact with the past and relay gravity data to his daughter, Murph.

A refresh rate of 370 microhertz gives "Calm Technology" a whole new meaning. I love it. https://en.wikipedia.org/wiki/Calm_technology

This is really interesting. Have you read Amber Case's book, "Calm Technology"? If so would you recommend.

This has to be the the most expensive cost per pixel display I've ever seen. And I've never loved a display more. This is absurd in the best possible way

I don't think I want to think of the actual cost per pixel - especially the cost of my time! I have deliberately avoided accounting the final cost

But the experience and feeling of building it... priceless. Money can't account for that.

And absolutely no energy consumption when you don't change the image.

It was directly inspired by e-ink, after all.

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.

This version of the Bad Apple meme[0] does just that, with physical apples: https://www.youtube.com/watch?v=lT-fdnIK0k0

This is pretty cool as-is, but I can't help but try to think up ways to increase the speed. (Not the point, I know.) I feel like it should be able to do a whole column pretty quickly with some optimizations. If the device that turns a block could do so without needing x-axis alignment to change, then you could do a whole column pretty quickly. Or perhaps it'd be better to do rows instead of columns, since the y-axis alignment shouldn't need to change with the current device. As for the block-turning device itself, I think some sort of thing that rotates would speed things up since you wouldn't need to reset, I think. I bet a manufacturing automation specialist could get this thing cruising...

BTW I love that you initially went with a very direct e-ink analog with the balls!
