A round window torn in St Michael. Behind it hang the things of these years: products, tools and systems for research.

AI content workbench · Product structure, agent workbench, front and back end
An AI content workbench for fashion brands: say one sentence, and out come the styling, the images and the copy. The model can only act through registered business tools.
Pick up an AI coding session from your computer on your phone, and see a session started on the phone appear on the computer. Works with Claude Code and Codex.
Through the arch at the end of the wall is the workshop, where every effect on this site was tried first: cloth, smoke, fire, crystal, lichen, compass and sound.

Michelangelo’s Pensieroso: like Dürer’s Melencolia I behind him, a picture of the melancholic mind at work. One 3D scan, drawn four ways: in the site’s own words, in engraved lines, in halftone dots, in one-bit dither.
The Demosthenes behind the lancet is set in the words of these essays: on agents and data, and on how this site was made.

Through the windows
The homepage of this site has no pages in the usual sense, only a path for a camera. The first screen is St Michael from Dürer’s Apocalypse. Scroll, and the camera dives into a round window torn in the print; behind it is the next picture, with the works hanging on it. Every chapter after that is entered through a window: an arch, a lancet, a quatrefoil, a row of stone arches, and finally a wall with five lancets.

Writing
A co-authored paper in finite geometry, getting ready for submission.
Learning
How to make agents review each other instead of agreeing with each other.
Reading
Two papers on the direction problem: Sziklai and Takáts on its extension, and Ball, Gács and Sziklai on the prime field.

I cut engravings in code, keep a diary in beats, and count directions in finite fields.
YIOYIO studies mathematics, working on finite geometry and additive codes, and writes software, mostly tools for AI agents and for data.
An AI content workbench for fashion brands, a small tool that lets a phone carry on a coding session from the computer, a pipeline that picks research problems, and this site. Beats too, released under the name Hades.

The last wall has five windows, each onto a place off this site: the scholarly record, the code, and a few works out in the world. Behind each hangs a glimpse of it.

Hades · Free your soul
Hades is the name I make beats under. Jacob’s ladder has fallen over into a table; incense rises from its quatrefoil, and the covers surface in the smoke.
