My app Photogenesis.app is now available. Made w/ React Native, @expo, @ReactNativeSkia and more, it lets you turn your photos into creative, animated, mathematically inspired art. 100% local. No AI. Full creative control! Would love you to try it! apps.apple.com/au/app/photoge…

New shader-based photo filter I've been working on yesterday & today. Lots of parameters going in (bloom, light streaks, halftone dots, color noise, chromatic ab, light streaks, etc.) so you can get quite unique results out of it depending on your choices.

Btw, that blue button you see enabled on the right is my new "Artistic Auto-Crop" setting which automatically crops images to try to create an interesting artistic result. Pretty cool if I do say so myself :-)

Working on a new effect today for Photogenesis.app ~ inspired by some recent sketching. I thought...wouldn't it be interesting to generate a polygon tessellation and then hatch each polygon. You can toggle to render the polygon edges or not for a unique effect.

@wavefnx For some reason this made me think of your art style @sinusoidalsnail 😂

Not now, s*ftware engineer, I'm writing firmware with my left hand while soldering with the right and controlling CAD with a neural headset to create gears Go to your room and play with your LLM-electron-webslop.js thingy Let The Man do The Job

I'm a little late to the party on this one since it's from January, but I just read this great blog post by Jure Triglav walking through implementing surfel-based global illumination. It's got a bunch of really cool interactive toys/visualizers! juretriglav.si/surfel-based-g…

Working on a new set of screenshots today for Photogenesis.app using this guide shared by @PaulSolt ... not sure if I nailed it, but I think much improved vs my current store listing :-)

@soycastic Nope, nothing like that appears. Using the mac app downloaded from the App Store.

@superligious Hello, you just need to select the text and a bar with customizing the selection will appear where you can change the color.

Hi, I’m Taras, and I’m building Screenshot Bro — a macOS app that takes the pain out of App Store and Google Play screenshots. Drop your screenshots in, wrap them in real device frames (iPhone, iPad, Mac, Android), edit captions across every locale at once, and upload directly to App Store Connect. 30+ languages with auto-translate, gradients, custom fonts, and iCloud sync. No Figma wrestling. No subscription traps. Built for indies who’d rather ship.

@soycastic Ok, had a play with it now...how can I change the color of just the selected text? eg. In your screenshots above you've got "GET BETTER RESULTS" and "RESULTS" is a different color ~ perhaps I'm an idiot but I can't figure out how to do that.

@superligious Thank you! I am always here for feedback!

@wcandillon pbr-book.org The classic! I’ve continually had it recommended to me for years now and just never found the time. Essentially derives how/why PBR rendering works etc. I think you would love it.

@superligious which book is that?

Just about to start my work-through of the classic Physically Based Rendering book ~ I want to implement everything from scratch in C++. Fairly intimidating...but I just recently finished Papa Rudin after 9+ months of continuous work so I have a thick skin at this point :-)

@thenoumenon Saw something like this just the other day actually: fragcoord.xyz/s/gouyatcw !

Neon-soaked procedural rain shader made with #tsl and #threejs

@reactiive_ Thank you! I learned so much stuff from your blog posts, shared code, etc over the years! 🙇

@superligious The app looks so cool 👏👏

So happy to share Photogenesis v1.5 is out now. This is a huge update - tons of new stuff! Every effect got a touch up, several new photo effects (like the one below), auto-crop, etc. Give it a go: photogenesis.app and remember to swipe left on the generated images!

Put together my first tutorial/guide for Photogenesis: How to make your own pixel art portraits ~ photogenesis.app/features/portr… Cool way to turn any photo on your phone into a pixel art image like this. This effect is totally free ~ give it a try 😀

@_esmenava @SnakeMGL Insanely cool :-)

I finalyyy redesigned my portfolio as a Gameboy game! I had this idea a few months ago and cant believe how it came out :) esmeraldanava.com Huge shout out to @SnakeMGL for the animation, I had a ton of fun working with your creation. #threejs

@sashabirukoff @raroque Yep, still an annoying problem honestly. Signed up to your waitlist :-)

built with @raroque waitlist here if you want early access halogenrecorder.com

excited to share what we’ve been working on recording beautiful iOS demos is still weirdly painful in 2026 Halogen is a native macOS app that sits next to your iOS Simulator and turns recordings into polished, shareable videos in seconds no confusing timeline. no AE. no workflow hacks just record and export

@yo_suke_ma2ura I love this! Elegant simplicity.

The Kinetic Mosaic effect in Photogenesis v1.5. It took about two weeks to build ~ first prototyping in p5.js then converting to Skia. The excitation feature was fun to build - randomly spawning nodes which propagate to neighbours, increasing their brightness & velocity.

This work was heavily inspired by works I've seen from @okazz_ from the p5.js community. Huge fan of their work ☺️

So excited to finally ship Kinetic Mosaic too 😀 In the v1.5 Photogenesis update I just submitted to the stores
