Centaur ELT: When a $10,000 Effect Becomes a Prompt

A door stopped me mid-scroll.

It belonged to 02ui.com — a blog archive rebuilt as a virtual art gallery, built with Claude, and put online by someone who’d clearly spent more time thinking about presentation than most people spend thinking about content. You walked into the gallery. You moved through it. The archive was the room.

I closed the tab, but the door kept reappearing: that familiar low-frequency hum that means something has caught.

When something catches, write it down before you talk yourself out of it.

I didn’t want the gallery. I wanted the idea buried inside it: that navigation through an archive could feel physical, that scrolling through old work might carry atmosphere if you let it. On this site, a “digital universe” already framed everything. It needed a journey. So I sketched one: a launch gate instead of a gallery door, a helmet, a wormhole, archived articles receding in chronological order, and at the far end — a black hole.

Scrolling became travelling.

That’s the centaur split in practice. I supplied the reference, the metaphor, the verdict on what felt right and what felt wrong. The AI supplied the implementation: the build, the image generation, the image-to-video conversion that turned a still frame of a black hole into something that pulls you toward it. I directed. It engineered. Neither of us would have done the other’s job nearly as well, and there’s no shame in saying so. Twenty-five years in ELT classrooms gives you taste. It doesn’t give you a rendering pipeline.

The sound effects went in during the edit. The whole sequence — the kind of thing that would have cost somewhere around $10,000 to commission before — cost the time it took to describe it clearly and the patience to iterate until the description was right. That change deserves a longer stare than most people give it. When production cost collapses to the price of a clear sentence, the bottleneck moves. It moves to taste. It moves to knowing what you’re after before you ask.

The swipe file is useful here.

I use Notion. The discipline is simple: when something stops your scroll, save it before you scroll on. Not to copy it. To remember the sensation it produced, and ask later what caused it. The gallery door produced a sensation. By the time I acted on it, that sensation had a brief attached: readers should feel like they’re travelling through time, not clicking through pages.

Inspiration plus taste is now sufficient instruction. The AI handles the rest. This is a habit that sits adjacent to what we do in language classrooms anyway — we train students to notice how effect is produced, to dissect a text until they understand why it lands. The swipe file applies the same discipline to your own practice. Save the thing that caught you. Annotate it. The annotation is the brief.

In this episode, you can watch the conversation with the AI unfold: the screenshots, the directives, the moments where I pushed back on a result that was almost right. Watch how much of the work is taste, and how little of it requires technical fluency.
