African Bricks: portraits built from thousands of fragments, inspired by the brick-and-colour patchwork of townships like Soweto, where colour is a declaration, not decoration. From across the room, a face. Up close, a wall of colour. My most collected series. #mosaic #portrait #ArtistsOnBluesky

Prosopon: This app uses InsightFace and Apple Vision to align eyes and mouths in various portraits. I have developed it for a personal project. If anyone needs it for any reason, just drop me a line, and I will email the DMG file. #MacApps

PDF is still one of the worst formats for LLMs. PDFs describe pages for humans, not information for machines. So columns get mixed. Tables collapse. Reading order becomes a guess. #Markdown is much better.

To convert my PDFs, I use Marker, the excellent open-source converter by Datalab. I use it so much that I started modifying it. Desktop interface. Real progress. Better batch conversion. Clear failure reports. No broken half-files. Some fixes are going back upstream too. #opensource

You fill a page with 40 sketches, or lay a whole icon set on one artboard. Then comes the tedious part: crop each one, center it, export it, type a filename. Forty times over. Shapearator does that for you. One sheet in, a clean asset library out. #computervision #opensource

I love Adobe Bridge. It's my favorite file browser. But it can't sort images by color. So I built an extension that does. BridgeColorShorter reads each image's actual palette (not just a single dominant pixel), groups your files by color family, and ramps each group from dark to light. #AdobeBridge

Your camera records the light falling on a face. What if it recorded the heat coming out of it? I made an app for that. It is called Heron. Give it a photo. It gives back an image that looks like it was captured by a machine beyond human sight. Thermal camera. X-ray. Night vision. Kirlian plate.

Same deal here. Real physics, but the images are art, not real thermography. I am in an experimental mood. I call it a system mosaic. Not one picture, a system that makes pictures, built from models, algorithms, and frameworks instead of glass tiles. Eight instruments. Sixteen palettes.

It is not a filter. It does not paint new colors on top. It deletes the lighting of the original photo, then rebuilds the image from what things are: skin, hair, metal, water, leaves, not from how they were lit.

The noise, the colour, the chaos: Billions of people surrendering to the same obsession at the same time. And here I am, quietly building images from thousands of tiny fragments, one by one, asking myself: why does this feel exactly the same? #FIFAWorldCup

Ever had a single file full of hand-drawn icons or shapes and wished you could automatically separate them into clean, individually named assets?

It can also enrich results with metadata injection and optional local model support through Ollama for semantic naming, all without relying on cloud APIs.

That’s exactly why I built Shapearator: a local-first tool that identifies shapes inside a PNG or SVG sheet, extracts them one by one, and organizes them into separate files with metadata.

In 1966, Bell Labs produced a portrait from electronic circuit symbols. Viewed up close, it was pure abstraction. Viewed from a distance, a human figure emerged.

Nature continuously invites us to zoom in and out, shifting between fragments and wholes, details and patterns, pixels and narratives. For the past 3 decades, I have explored that territory with a little help from science, math, and technology.

The work was controversial enough to disappear quickly, but the problem it revealed would endure: how can meaning arise from the accumulation of discrete, locally insignificant parts?

I made a new open-source app called Hipparchus. It creates clean vector maps from OpenStreetMap data and exports them as layered SVG files. That means roads, buildings, water, parks, labels, railways, coastlines, and other elements stay separate and editable.

Dear friends, I just released Skiagrafia: a desktop app for batch-generating masks and vector silhouettes from folders of images. Repo: github.com/tsevis/skiag...

I've officially upgraded to the Qwen Coding Plan via Alibaba Cloud. While the initial setup required a bit more effort than anticipated, the value proposition is undeniable: access to 8 models for just $10/month. #AICoding
