Inspired by a recent Spectral Collective video published on 3B1B's channel, I've implemented a simple version of the liquid-vapor model:
chalier.fr/generative-a...
Move the mouse to change params, scroll for speed, left/right click to add/remove particles, press S/R to screenshot/record the screen.

A few weeks ago, I published the version 1.11 of Transflow, which generalizes the way pixel sources behave with a nice 'Compositor' framework. Mainly, Transflow should now be easier to use, even for more advanced effects. I've also updated the documentation with more examples, for you to try it out.

I've just pushed the v1.10 of Transflow. Not a lot a new features, I've tried to clean up the code and make it more structured: github.com/ychalier/tra...
The next update should also be a refactoring, I would like to unify the multiple accumulation methods into a cleaner, general class. Stay tuned!

Just released v1.9.0 of Transflow, with a brand new GUI! If you're afraid of command line interfaces, this should make your life easier.
Beware, though, this is still experimental, bugs may/will arise.

I've just added an audio reactive feature to my randomart webapp.
In short, you can use specific variable names in the grammar to refer to the (normalized) intensity of ranges of the frequency spectrum (e.g. low, mid & hi).
Here's a sneakpeak:

2y ago, I built a tool to generate halftone images, inspired by a paper about halftone QR codes.
Lately, I've wanted to use this technique to embed a QR code within an halftone image. I found an old repo on GitHub, refactored it and added my scripts:

I tweaked Transflow to replicate the 'sticky texture' effect of regular datamoshing. The code is a bit dirty but the result is nice! Here are three clips pasted together:

Just learned about LiDAR HD data by IGN, a point cloud mapping of most of surface of France. It's really cool, and freely available! Visualization made with QGIS 3D Viewer.

Motion Interference. Applying the reversed flow on the same video makes pixels relatively static while revealing some of the transformations – e.g. through perspective change or flow inaccuracies. Thought for later: is there a motion equivalent of the Moiré effect?

Been trying out Deforum for generating videos with Stable Diffusion. It's great at textured and abstract drawings.

I've been playing around with a public webcam recording 30s clips every 5min of a pedestrian area, and blending those clips together. Here's an example with an (about) 8 hours span (94 clips).
Also, you may try to find that place, it should be pretty easy!

Well, my FlowNet2 integration attempt was not successful: I had a lot of issues with installing dependencies and finding compatible module versions.
However, I managed to integrate LiteFlowNet, a more recent alternative, which also provides very high quality results!

I tried to use a MPEG-4 Part 2 video codec (Xvid) instead of h264 for my datamoshing script that removes I-Frames from the bitstream. Results are much more interesting! h264 really was too resilient! and frames would heal instantly. Now they're crushed, as they should be.

Transflow update v1.6! Lately, I've been working on new features, mainly to support other optical flow algorithms. Then, the only option was Farnebäck's algorithm, OpenCV's solution for dense flow fields. I've now added support for Lukas-Kanade and Horn-Schunck methods.

Been working on a new feature for Transflow, to provide a way to move things more progressively and avoid unpleasant blinking. In the example below, new pixels are introduced in the rightmost column, and then moved around with the optical flow. Will release it soon with other minor fixes!

I learned that Audacity can be somewhat automate with the mod-script-pipe module, so I tried to produce frame-by-frame moshed videos with it. I added it to my datamoshing repo on GitHub: github.com/ychalier/dat...
For anyone also interested in databending/datamoshing: a great starting tool is audacity.
Save an image as a .bmp or .tif
Use audacity to import raw data, u-law, little-endian
Leave the first 3 or so % alone
Mess with 'Filter Curve EQ'

In last Transflow version, I added an automatic upscaling feature for using small video inputs. E.g. a 128*72 flow can be applied to a 1920*1080 image by counting 15*15 blocks. Besides being faster, it also gets closer to the original datamoshing look and feel, which mostly relies on macroblocks.
