Things I built for fun

Small, self-contained web toys — no accounts, no tracking, just open and play. Each one is hand-built in vanilla JavaScript and shares this site's dark mode.

The ensō calendar — a month grid of daily brushstroke circles

Daily · generative

The Daily Ensō

A new brushstroke circle every UTC day, deterministic from the date, with a one-line AI impression of its mood. Past days fill the calendar; tomorrow is still blank.

Tool

The Ensō editor

Every brush, ink, color, and shape parameter on a slider — re-roll, save presets, and open any day's ensō to tweak it. Open the editor →

Puzzle

Spectrum Sudoku

Sudoku, but the digits are colors. A fresh, fully-responsive take on the classic.
