Great post! Here's one from Keith Peters with some interactive code examples: https://www.bit-101.com/blog/2022/01/circle-inversion/

You can export sprite sheets from animations created in the Adobe Flash authoring tool. There are a number of free third party tools that enable this:
SWFSheet

This feature is also being built into the next version of Flash Professional (the authoring tool), with support for export to various JavaScript libraries (such as Easel.JS) for controlling the animation.

it might be some swfsheet (http://www.bit-101.com/blog/?p=2948) type of software. Having that sprite (what a design!!!), you can animate it with jquery easily...

"maybe such a high pixel density is unnecessary with e-ink?"
That's right. E-ink pixels are not square, don't have gaps, and don't use three colour pixels to create white. A higher pixel density with e-ink would be nice, but isn't as necessary as it is with LCD.
