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. 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.

Interactive · heliophysics

Solar Corona & Wind

The Sun's corona, magnetic field, and solar wind streaming outward in real time. Drag the solar cycle slider to reorganize the magnetic topology, and toggle Alfvén waves and AIA-style false-color filters.

Bonus · live

The Sun, right now

Not a toy exactly, but alive: up-to-the-hour solar imagery processed with my own method. Go look at the Sun →
