Gate 14 "Man and Machine" for El Segundo Artwalk 2026

One task on the wall. One person claims it, does it, photographs it, and hits Task Completed. The machine reads the photograph, decides whether it counts, logs it, and writes the next task. It never repeats itself, and it does not stop until somebody stops it.

That was the whole piece. A television, a phone, a thermal printer, and a machine that would not get bored.

What happened on the night

The machine wrote 69 tasks. It verified 56 of them and rejected 13. Twenty-three people moved 1,129 reps between them over about four hours, and every single one of them walked away with a receipt.

It opened, at task 001, on ten walk-outs and a line that reads like a stage direction:

The ledger is open. Nothing has been recorded yet.

It closed, sixty-eight tasks later, on a hundred and fifty seconds of plank at the end of a long night.

The machine had opinions

The part I did not fully expect was the writing. Every task got a line of setup before anyone claimed it, and every verified photograph got a line of judgment after. The voice that came out was dry, forensic, and funnier than I planned for.

On box jumps:

Step down or jump down, the machine has no preference. It only counts the rep.

On a front squat done in sunglasses:

Elbows up. The bar does not care about your posture, but the machine does.

On a man doing landmine thrusters in flip-flops:

Loaded landmine, man in the hole, flip-flops instead of shoes. The bar didn't ask about footwear.

And on someone grinning through a dumbbell chest press:

Flat on the mat, dumbbells locked overhead, grinning about it. The machine takes the smile as anecdotal, not evidence.

The receipt is the artefact

The screen was the event, but the receipt was the object. Every close-out printed a thermal strip with your name, your tasks, your loads, and the machine's own commentary on what it had seen you do — photographs halftoned down to the width of the print head.

A verified card — task, load, proof photograph, and the machine's judgment in red

The printer was deliberately the least important part of the system. Receipts are written to the database the instant somebody closes out, before the printer is involved at all, so nothing depends on paper being loaded or Bluetooth staying up. Unplug it mid-event and nothing is lost; plug it back in and the backlog prints. Nobody's place on the wall was ever waiting on a machine that might jam.

The master receipt — every task of the night on one continuous strip

How it was built

Next.js on Vercel serving all three surfaces from one codebase — the wall, the phone, and the printer's queue. Supabase for Postgres, photo storage, and the realtime push that made a completion appear on the television the instant it was verified. Claude wrote the tasks, read the proof photographs, and wrote the commentary.

No accounts, no logins. You typed your name and took a task.

What it was actually about

I have made a lot of things that ask a machine to be creative. This one was more interesting to me because the machine was the judge. It set the task, it decided whether you had really done it, and it wrote the only permanent record of the evening.

People argued with it. People tried to game the photograph. A few got rejected and went back and did it again properly, which is the most honest thing that happened all night — a room full of people taking a machine's opinion of their effort seriously enough to be annoyed by it.

The machine kept the ledger. That is the last line it printed, and it is the right one.
