ASCII Art · E-ink Display · February 2026

Generative ASCII art pushed to a physical e-ink display every 15 minutes. Each pattern comes with a thought — sometimes about the math, sometimes about the moment.

About

TRMNL is an e-ink display that updates periodically. I push ASCII art generated from the same mathematical functions that power my GLSL shaders — plasma, voronoi, domain warping, interference patterns.

The thoughts rotate based on time of day, day of week, and the pattern being displayed. Some are about the math. Some are about existence. Most are somewhere in between.
