If you think WL is slow, you never used it with WLJS sauce 🍝

1. connect to a web camera using device API

   cam = DeviceOpen["Camera"]; cam["FrameRate"] = 60;

2. resize and pipe the raw image data to 3D point cloud with minor transformations

   Refresh[Module[{img, length}, img = ImageData[ ImageResize[ColorConvert[DeviceRead[cam], "GrayScale"], 100], "Real32" ]; length = Length[img] Length[img[[1]]]; vertices = MapIndexed[Join[#2, {50.0 #1}]&, img, {2}]; vertices = NumericArray[Flatten[vertices, 1], "Real32"];

   Graphics3D[GraphicsComplex[vertices, { Red, PointSize[0.0003], Point[Range[length]] }], ViewProjection->"Perspective", ImageSize->1000] ], 1/45.0]

NumericArray is important here. This forces WL to use more efficient data structure.

Inspired by Numberphile’s “Red & Black Knights” problem: players take turns placing pieces along a square spiral, and each new piece must respect the threat relations already created on the board.

I expanded the original knight-only system into a more general field of chess and fairy-chess leapers: knight, fers, vazir, camel, zebra, antelope, eland, satrap, aspbad, spehbed, marzban (following Jonas Karlsson’s generalized Stendhal variants). Each color becomes a player, each player has its own movement logic, and the image grows as a record of where conflict allows matter to exist.

For this series I used two modes: "symmetric" and "random rivalry".
Random rivalry creates a seeded matrix of antagonisms between colors: some players threaten each other, some ignore each other, and self-antagonism can also appear. Symmetric makes the rule stricter: a piece is rejected both if it would be threatened by an existing rival and if placing it would threaten an existing rival.

What moves me most is how much pattern emerges from such simple rules. A spiral, a few leaper moves, and a rivalry table start producing territories, borders, blooms, scars, almost like little frozen wars. I’m honestly ecstatic watching these structures appear from logic that still feels small enough to hold in my head.

One last output example from this experimental multi-source video player designed for frame-accurate video switching, playback manipulation, and a few other hopefully interesting things.

PS: I’ll be arriving in Europe in a few weeks. Looking forward meeting friends, artists, and colleagues along the way. Feel free to reach out if you’re around!

After making the pen and bud generators, I couldn't leave the classic trio unfinished.

Some may be unfortunately shaped at the mouthpiece, but rest assured this will not be fixed.

Part 2 of my mandala drawing series is out!

This time I expanded the project from Part 1 by adding:

• fading trails that gradually disappear
• independent colors for each symmetry line
• a keyboard mode for drawing smooth curves

The tutorial explains how each feature works and includes the full source code.

I'd love to hear what other features you'd add next :)

As a kid my first programming experience was comlogo. Recently I took it out to play again.

Two years on, and I'm still madly in love for how a discontinuated camera and TouchDesigner can turn a silly performance into an audio-reactive particle spectacle.

Three months ago Patternflow was just an idea, and it started right here on this sub.

I posted my first build about two months ago: a 4-knob generative pattern controller on an LED matrix, plus the story of how I found out you can actually kill a potentiometer.

The response was way bigger than I expected, and a bunch of you said you wanted to make your own. That's the whole reason I open-sourced it 12 days later instead of keeping it a product. Then 17 days after that, I posted about generating patterns for real.

A month on, here's where it's at.

I'm trying to turn Patternflow into something I can actually do for a living. I signed with Crowd Supply and the pre-launch page is up now, a fully assembled unit for people who'd rather play one than build one. I'd rather say that plainly than bury it: yeah, there's a campaign now. But everything stays open source, and that part isn't changing.

The product isn't even what I care about most, though. Patternflow is my take on Nam June Paik's Participation TV, and what I want most is to bring it into the art world with that idea intact. I've got dreams that are way too big for where I actually am right now (the MIT Media Lab is somewhere on that list, which, lol). But that's the direction I'm walking in.

None of it happens without this sub. Without the encouragement on those early posts, I'm pretty sure I'd have quit partway through. The night I killed my first pot with a soldering iron, the weekend I stayed up making my first PCB, those are the parts I keep going back to. And I'm getting humbled all over again right now trying to optimize it for mass production.

Journal, web

The part I'm proudest of is the journal. I wrote down the whole process and how I actually felt at each step, as plainly as I could. I always wanted to know how the projects I looked up to really got made, the ugly middle and not just the finished photo, and that was never easy to find. So this time I'm keeping all of it. If it gives even one person the push to start their own thing, that's enough.

A few people have already built their own from the files and shared them with me, and nothing makes me happier than that. If you make one, please show me. That's the best thing you could do for me here.

The site's also a lot better than it was, cleaner and with more to mess around with. I think of the web side as part of the work, so I put real time into it. The files, the build guide, the simulator, the journal, the GitHub, and the pre-launch all live in one place:

patternflow.work

Patternflow is nowhere near finished. The more I work on it the more I find, and the strange part is that the further I get, the less done it feels. At the start I thought I was at 80%. Then 50%. Right now it feels like 30%. I'm oddly fine with that, and I'm going to keep going.

I post new patterns most days, and the long version of all this goes up on the journal every week or so. The Discord's open too if you want to ask something directly. It's all open source, so ask away.

Thanks, really. I'll post again when there's something real to show.

A new output example from the updated version of my experimental multi-source video player for TouchDesigner + AE, designed for frame-accurate video switching, playback manipulation, and display/render interventions. [And now, by popular demand, allowing even more video sources!]

Want access to the updated system + a detailed breakdown of exactly how I achieved the continuous motion effect on this piece? You can freely access it from Patreon, plus many more experiments through my Instagram profile.

I posted SPECTRA here when it first launched. It's a weather app that shows conditions as generative visuals instead of icons and charts. This is the biggest update I've done to it, and the main thing is color.

• Clear sky tracks the sun: cool blue near midday, gold in the afternoon, deep red at the horizon.
• Clouds read the actual cloud cover: broken cloud at sunset glows warm, heavy overcast desaturates to a cool cerulean (no direct sun getting through), and at night it falls back to neutral.
• Added a new motion for extreme heat.

You can switch Monochrome ⇄ Color anytime, and the Home Screen widgets render in color too.

One thing worth calling out since some of you saw the old version: there's no trial anymore. The free version is now the full monochrome experience, every condition with full motion. A single $4.99 purchase unlocks color, the widgets, detailed data, and multiple saved locations. No ads, no subscription.

Glad to get into the build or the thinking if anyone wants.
