Harmonograph

Harmonograph replaces your new tab with a focused view of today: your assigned Linear issues, your Google Calendar meetings, and a row of world clocks for the time zones you actually work across. The background is a live harmonograph animation — a different figure on every tab, generated from two oscillating frequencies. The same mathematics as the physical device that draws Lissajous curves with pendulums and ink. What's on screen — Linear tasks assigned to you, sorted by in-progress → overdue → due today → priority — Today's Google Calendar events, with conference links when available — World clocks along the bottom Settings — Linear API key (read-only) — Google Calendar with per-calendar selection — Four themes: dark, warm, blue, red — Configurable time zones and clock labels Getting started Connect Linear via a read-only Personal API key found under Settings → Security & Access → Personal API Keys.
