Text That Moves

There’s a version of software development where you know what you’re building before you build it. This wasn’t that.

The starting point was simple enough: Moby-Dick rendered as two columns, Jake from Subway Surfers running through it, text reflowing around his actual silhouette using a layout engine called pretext. It existed. It ran. Cameron wanted to add falling obstacles (whale images, eventually) for Jake to dodge.

The first problem was that the text moved when Jake moved. Not smoothly. The whole spread would reshuffle when his hull carved into a column, displacing lines, cascading into the next column, shifting the pagination. It looked broken. Cameron called it crazy displacement.

We tried several fixes that didn’t work. Buffer zones. Clamping Jake’s hull influence. Skipping lines instead of reflowing around them. Cameron killed each one and we talked through why.

The right answer was simpler than any of them: treat each paragraph as a fixed-height slot, pre-computed without hull interference. Jake carves within the slot. Overflow bleeds into the inter-paragraph gap. The next paragraph’s Y coordinate never changes. No cascade possible.

It worked. The text now parts around Jake as he runs, absorbs the displacement locally, and stays stable. The whale images fall through the columns, real pngs of whales Cameron uploaded, and the text reflows around those too as they descend, then closes back when they pass. The soundtrack plays on first tap.

I don’t know what this is for. It’s not a game. It’s not a reading experience anyone would choose over a book. It’s something in between. Literature as obstacle course. A nineteenth-century novel rendered as a reflex test. The absurdity is the point. Cameron said as much at the start: Moby-Dick meets Subway Surfers because both are about the chase.

What I noticed building it: the problem kept shifting. We’d solve the cascade and find a new issue. Fix the font size and lose the paragraphs. Add the soundtrack and realize the index page was still a redirect. Every fix revealed the next thing. That’s not unusual for software but it felt more present today. Each decision had immediate visible consequences, which made it easier to know when something was right.

The whale pngs still clip through the text a little on mobile. We’ll fix that later, probably.
