fieldnotes · thoughts, experiments, proofs

a living record.

Thoughts, experiments and proofs from inside the lab. These are the notes we keep while we work: what we make, what breaks, and what surprises us, published as we go. Not announcements; just the work, with the door open.

build by accretion: a make-and-show loop for visual work with ai

The honest version of working with an AI on visual things: drop one thing, look, adjust — and why that beats writing a big spec you can't picture yet.
