We really need a short for "is it AI or not? has entered the discussion".

The others are nice (but hectic) animations to me.

"Yes, but not natively just by using a standard <img> tag in web browsers. Because native APNGs play continuously like a traditional GIF, you need to use one of the following methods to pause them: [1, 2, 3, 4]

1. The Canvas Method (Best for Web Controls) To add play/pause functionality, you cannot use an <img> tag. Instead, you need to render the APNG onto an HTML <canvas> element and control it using a JavaScript library like apng-js. This provides precise, video-like control over the frames. [1, 2, 3, 4]

2. The Cover Method (Simplest Fallback) If you just want to freeze an APNG on its first frame, you can layer a static .png of the first frame directly over the APNG. When you uncover or hide the static image, the underlying APNG will be revealed and play as normal. [1]

3. Use CSS Animation Alternatives [1] If you are designing the animation yourself, an alternative is to build it as a single static image (a filmstrip of all frames side-by-side) and animate it using CSS background-position. This allows you to pause the image natively using the CSS animation-play-state property. [1, 2, 3]"

Inside of every old man, is a young man, going ”What the hell just happened?”.

These days you can just capture video and make a 4d Gaussian splat

It's really a completely different effect to just stitching a few different photos together.

If you pick up a digital stereo camera that creates .MPO files, I wrote a small app to create stereograms: https://github.com/EngineersNeedArt/Stereographer

Other than getting used to making the switch, I don't think there is any cognitive load. Just pairing normal lens focus with a different triangulation distance, which is something we quickly learn to do without thinking when using any glasses or lenses.

I find it a lot more calming than Wiggle-D. And paired with some simple head/eye tracking via laptop cams, it could be really versatile.

The animated plots are great. Be great to have a trackpad rotatable version. (And the need/benefit for head tracking gets really obvious when I move. The perception of reverse/non-sensical dynamics is strong.)

image formats are more backward compatible, but at some point one has to ask, how low do you want to go? vp9 plays on iphones from 2020 and android phones from 2010. I think animated avif files are basically av1 video files, like animated webp is vp8/9 video.

Animated gif is playable anywhere, but 10x bigger. For a wiggle blog or website I'd provide animated png alongside anaglyph, or anaglyph only.

There is also animated Jpeg XL *.jxl files for the bleeding edge. It's a pure image format but support is not there yet.

The unintentional ones deviate on both bases, creating a more chaotic result.

("Creating chaos" being an interesting notion itself....)

I've been taking pictures to be more effective wigglegrams now that I know I can auto-GIF them. I'll do a followup post at some point. The big trick is that they look better when the subject stays in the center of the frame, with the camera "orbiting" it to create a sort of parallax effect.

(The original defaulted to “past 24 hours” for me, which didn’t show anything.)

Sites/apps like Discord sometimes consume the mp4 instead of gif or webp when embedding (and in Discord's case they're not hotlinking, I believe they're running it through their own media proxy service).

For example, <https://klipy.com/gifs/begone-witch> turns into <video> (with ARIA GIF label!) and src <https://images-ext-1.discordapp.net/external/kQT1eR3Sa6g3mZ_...>

7.1 MB gif => 679 KB mp4

Thanks for the response and I agree there are benefits to newer formats. I actually do prefer newer codecs when I am using a newer system, such as AV1 (I actually wrote a blog post on that yesterday https://inavoyage.blogspot.com/2026/06/720p-on-384kbps-how-h...), and recall avif, but forgot about it.

I think .avif sounds preferrable since it is single frames able to play animations using the same library as av01. I am curious how much CPU usage it needs for a just a few frames. A Pentium 1 might not be able to play it easily, but I imagine a dual core Intel E6400 wouldn't have much of an issue, even if it is 20 years old.

Yeah, basically the only reason I suggested older support was because it was just a couple frames (maybe 5 tops), as opposed to something that uses hundreds or thousands of frames.
