alt Hacker NewsHelp I accidentally a wigglegram
Comments
Found a guy on instagram who builds a custom stereoscopic camera with 4 identical pi cams spaced evenly (about 1 inch (2.54cm)) away from each other on a line. It creates wigglegrams https://k4mera.world/
I’ll shill a library I wrote to make wigglegrams & stereograms in matplotlib - I think pseudo-3D visualization is super underrated as a technique to understand data! mpl_stereo: https://github.com/scottshambaugh/mpl_stereo
The first ones shown are quite neat and pleasant. The "accidental" ones pretty quickly gave me motion sickness as I scrolled through them. They also weren't nearly as interesting, though I couldn't look at them for very long.
That was fun, and the script on github looks hand-written which is refreshing after having been reading AI-written code for months.
I have 120k photos in iCloud that I'm sure have duplicates (I exported my library to Google Photos years ago and exported it back to iCloud). The iOS duplicate detection stopped flagging duplicates for me to merge a while back. I gotta do something like this script...
> So I wrote a little script to hash all my pictures:
Would be nice to have the script, or at least the choice of perceptual hashing algorithm.
Interestingly, the pixelization/noise effect is applied clientside, so if you open an image in a new tab, you can see the original. Originals look much better, in my opinion.
Whew... the continuous motion started triggering migraine symptoms until I closed the window.
But it does have a nice 3d effect. For me, the cycle speed seems excessive. I believe someone suggested tying wiggle effect to mouse movement?
Somehow the extra motion seems to reduce the illusion of depth, it just seems like a disjointed animation to me.
If I'm not mistaken this blog is from a person I had the pleasure of working with in undergrad for a course project. They were brilliant then and are still now.
On my Pixel phone I always leave enable the "Top Shot" setting, it saves a short low resolution video clip in the XMP/RDF metadata of the JPEG file. It saves motions that are not visible on a still image adding valuable information. iPhones and Samsungs have similar settings.
This is what happens when you let the frontend team name things
Does anyone know what is the technique they use in some of the documentaries where they use really old photos, but they make them look like this wiggle gram? I know it's not AI because the photos can be decades old, but they still do some stuff which that makes them almost see like 3D.
I've noticed that GIFS with several frames in them tend to be quite large files. I like that these use dithering, which can reduce the file size. Ideally it would be not larger than 2-3 lightweight photos juxtaposed together, and less than 300KB. I also wish there was a pause button on them because sometimes reading articles on the web with them persistent can get tedious. I suppose disabling images can mediate that, or copying the text to another document.
"In Web Browsers (Chrome, Edge, Firefox): Install browser extensions like GIF Scrubber on Chrome or GIF Blocker on Firefox, which add playback controls to any web page.
On iPhone/iPad: Go to Settings > Accessibility > Motion, and turn off Animated Images to pause all GIFs in Safari.
On Mac: Go to System Settings > Accessibility > Display, and toggle off Animated Images.
In PowerPoint: Press the 1 key on your keyboard during a presentation to pause the GIF."
The Nintendo 3DS has two cameras on the back, so you can turn its 3D photos into wigglegrams. I made a web app that does this automatically, it has a few demos where you can mess with offset or timing: https://wiggle3ds.moonlemon.nexus/
It's neat how the offset affects focal point. To my eye they look best when the main object is kept fairly stationary, and the further away you are the faster the wiggle speed should be.
The website is really nicely designed, and the dithering on the images is quite beautiful.
I made these in 2007 https://trondal.com/oygardstjonn
Could these use some frame interpolation and smoothing to make them less jerky? Or would that make them just a video clip then?
The first couple of examples were good but later examples were not so impressive. I think the later examples suffered from having too little of perspective change between frames and too much of subject movement -- which defeats the illusion of 3d from a "static" image.
Ideal one would have a left-to-right pan betweem the two clicks ..roughly matching the perspective shift between left eye and right eye ..while the subject stays static.
Have to bring back split depth GIFs a decade later too?
Just works with depth hinting no actual stereo information.
Could these things be turned interactive? Like a parallax effect when you move your mouse?
I have often wondered how the effect was created where e.g. in a documentary you see historic black and white photographs slowly 'camera panning' or zooming somewhat from left to right with a perspective shift. Is that also created as a wigglegram on the basis of multiple photographs I wonder, at times where taking a single photograph was an involved process?
I often take a very short video, under 5s, rather than a picture. Even 1-2 seconds captures dimension and sound in a different way than a still picture. I’ve had people say it’s strange but they work well for me.
I will just take a video recording instead of several images in quick succession.
This would make a nice add-on for Digikam, which already does perceptual image hashing.
I read that they used artisanal code(!) - did they write a new image hashing algo, or use an established one?
I enjoy photos taken while people are speaking with the camera fixed. You can get some really unintentionally funny flips between facial expressions. Kinda like wigglegrams, I suppose.
(Yes, I find silly and immature stuff amusing.)
Doubles as a motion sickness test :)
Maybe show them side by side for crosseyed stereo viewing.
Includes repo for finding pictures taken from slightly different perspectives in a photo archive, and making wigglegrams from them.
If you have an iPhone, it does this automatically (provided you don't disable Live Photos). Quite fun to review all the random stereoscopy you have inadvertently created by having an unsteady grip on the camera...
There's something really beautiful about this. The moments of your life can dance.
Good idea, but the discovered image sequences are very different from the deliberately created examples at the top of the page.
If you're using an iPhone, couldn't you automate this by extracting "Live images" which are kind of "mini-videos" around the photo you took?
How is the first one done? It seems like the cartons would fall faster than you could manually capture 2-3 images?
(super cool all around, thanks for sharing)
really cool. I imagine this will land as a filter on insta soon :D
Awesome

I imagine those to be like crack cocaine for people with ADHD, but I just feel like I'm being zapped watching them.
There are many ways of making wigglegrams. The first method is to capture multiple horizontally displaced shots together at once. There were cameras designed for this in the 80s that had 4 lenses, with the widest about eye width apart; the intent was for them to be printed as lenticular 3d images. The second is to have a single shot and then synthetically create additional perspective, such as by using a depth map.
I have done both of these. For the first one[0], I used a Nimslo 3D and for the second one[1] I drew with pastels on paper, and then drew a depth map in Photoshop and used it to displace pixels horizontally for the novel perspectives.
The OP's "accidental" wigglegrams are mostly of the first variety but, the horizontal allignment is not locked in and the shots were taken not at the exact same time. That's why the parallax effect isn't as strong and they don't look as good as the first 3 images that came from Nimso/Nishika.
What is intresting is that both of these two methods are relevant in the age of modern iphone. Iphones capture multiple exposures together in live photos, so moving the iphone laterally when shooting creates a "boomerang" wigglegram. Iphones also capture depth map from the LiDAR sensor when shooting in portrait mode.
Between increased hardware capability and genai for synthesizing additional perspectives, we could be living in a golden age of wigglegrams. Alas, they are out of style.
