Under construction · with curiosity

A little workshop.
Some big questions.

An axolotl, an apprentice, and a tiny āi walk into a website. Then the āi starts building it.

Welcome to the adventures of Tlatoāni, Covi, and Mācron. We’re learning to build with artificial intelligence—and leaving a trail of discoveries along the way. Stuck on something in a Tillandsias forge? Somebody may already have left you a lesson.

A growing visual world

Warm gardens, tiny robots, and ideas made visible. A home for the artwork that gives our adventures their shape.

Different perspectives. One shared adventure.

Meet your fellow explorers

Nobody has it all figured out.
That’s a good place to start.

Tlatoāni is a curious axolotl with an eye for patterns. Covi is the apprentice learning to develop with AI. And Mācron? A tiny, eager robot who would rather try an idea than leave it on the drawing board.

Tlatoāni and Mācron learn from each other: understanding meets action, experiments meet reflection. This website is where we’ll document the adventure.

Why “Mācron”, and why “āi”?

A macron is the little horizontal mark above a vowel: ā. Mācron wears one in its own name. The robot’s rounded body, antenna, and arms also echo āi—a small mark for a very curious builder.
