Seeds and regret
Every piece here is one integer away from a different piece. Losing that integer is the only unrecoverable mistake in this work.
The first year I generated straight from the system clock and saved only the output. Then a drawing came out that I liked more than anything before it, and there was no way back to it. Now the seed is written into the filename, the metadata and the corner of the plot itself.
Storing the seed is not enough on its own. The generator has to be pinned too — a change in how a random number is drawn shifts every piece that came before it. I keep the generator in the repository and tag the version alongside each series.
The upside is that the archive becomes tiny. A thousand pieces are a thousand numbers and one program, not a folder of exports.
