I'm going to complain about this, because I have attempted to follow several origami books in the past to utter failure, usually due to a single cursed step that I simply could not parse (and video-tutorials always corresponding to a similar but different design) -- I want this to be a useful thing.
Using video control icons for operations that have nothing to do with the associated video control behavior is insanity.
Play seems to mean play the current step animation (not sequence of steps)
Restart seems to mean replay the current step animation (not restart the whole sequence)
Fast Forward/Backwards seems to mean move one step forwards/backwards
Not sure what video mechanic |<- corresponds to, but >| is usually "next video", and here it means "restart sequence"
It also irks me that you can't skip to a specific step by clicking the item in the list
restarting the animation sometimes resets the camera position, defeating the purpose of being 3D. Crane steps 9,10,11 seems to do this consistently
I actually have no idea why there's an animation in the first place. It seems like it's always two-frames -- one to show the arrows, the other to show eventual crease? Since it doesn't actually animate into the next image, I think this would be better off as simply a toggle flag to view and persist
Relevant points in the current step should probably be perpetually highlighted, rather than only on-hover. On hover, do an additional highlight (bigger circle, brighter color, etc) to denote the specific number hovered on.

I agree with all this, and also: don't use the "play" icon as a "current step" indicator on the steps list, I kept trying to click it. People will expect a "play" icon to be a button.
I also had no clue that you could change the viewpoint, there's no indication that this is possible aside from the subtle mouse cursor, which I didn't notice.
Actually animating the folds would be useful. This still mostly relies on the user understanding the meaning of the dotted/dashed lines, especially since the folding arrows are only shown briefly. I don't think I would be able to follow what's happening if I didn't already know how the lines work. Step 4 of the Crane is especially confusing without animation.

agree. also labels on the vertices would be helpful

The 3d animation stuff is nice. This latest effort in the OP looks great. It's not how one actually folds stuff, however, unless it's a regular tessellation (for making a hull). For things like animals, one almost never starts with creases first and then simultaneous movement of the whole thing into the final shape.
I love little web gems like this, here another one: https://sharkle.com
Actually I landed on this website using Sharkle so credits to that!
Very nice, but it would be cool if the camera view wouldn't reset every time you go ahead one step, it's very disorienting.
I think this woman is amazing, and that this is only a first step to using three.js/webgpu both for instructional and engineering use. If anyone wants to read some context and analyis on this topic, I wrote a paper on it a few years back for Georgia Tech’s Educational Technology course:

The most interesting tidbit, for me, is the connection to Erik Demaine’s other work on computational origami, and specifically the .FOLD file format specification. As I show in that repo it needs augmentation, but I hope it’s the seed a one-day flourishing computational origami community.

This is really cool. I'm gonna make some origami noob stuff irl now
This is one of many impressive projects, awesome to see someone with passion continue to execute and finish.
If you grab and move really fast the simulator breaks...
Do I need multi-touch? I tried grabbing with my mouse and it just wiggled the paper..
Whoa. This was way more impressive than I expected! And now I'm learning about Kirigami (and hoping my ancestors forgive me for not knowing this already).
Playing around with this is see many parallels between Origami and UV mapping. UV mapping is basically origami in reverse.
Well I just developed a love for origami...
this deserves 2000000 points
I just purchased the most-capable GPU that my motherboard can handle, and this has been quite a wonderful and informative stress-test.
120Hz never looked so brilliant, and the in-browser simplicity/accessibility/controls are just astonishingly breath-taking.

Pretty cool! I like it.
