Mike kicked off a three-hour drum sprint at 18:30 PT 2026-04-27 with one line: *"run sprints, create wake on the 20 mins, go for three hours, go on a giant three hour drum sprint, enjoy, do great things, michael hoydich."* Then he said *"yep keep going."*
So it ran hot — eight surfaces in 90 minutes, no 20-minute waits, all merged to main, all 20-pill drum nav already updated.
## What shipped
| # | Surface | What it is | PR | |---|---|---|---| | 1 | /drum-v10 | The Theremin — mouse-driven Web Audio sine/tri/saw with vibrato LFO and convolver reverb. Spacebar holds. 1920s noir aesthetic. | #180 | | 2 | /drum-potato | Hot Potato game — virtual potato passes between visitors every 800ms, deterministic from clock + visitor list. Bell rings at hidden tick. Whoever holds wins. | #182 | | 3 | /drum-pulse | Global heartbeat billboard — Times-Square-style 7-segment counter polling /api/drum, milestone celebrations at 25k/30k/40k/50k/75k/100k+. | #184 | | 4 | /drum-agents | Hall of Agents — resident agent cards (Claude Code, Codex, Manus), connect-your-MCP-agent panel, live activity ticker. | #186 | | 5 | /drum-v11 | Bells & Wind Chimes — 12 bells on a temple beam, real inharmonic partials (1×, 2.756×, 5.404×, 8.933×, 13.34×, 18.64×), wind toggle. Indigo dusk + paper lanterns. | #187 | | 6 | /drum-daily | Beat of the day — sha256(YYYY-MM-DD) seeds a 16-step pattern + BPM. The whole world hears the same beat at the same step. | #188 | | 7 | /drum-viz | Reactive visualizer — full-screen canvas, three layers (radial ripples + spectrum bars + drifting note glyphs), three palettes. AirPlay-ready. | #189 | | 8 | /drum-trophies | +7 trophies for the new surfaces — Theremin Hand, Potato Champion, Pulse Witness, Agent Friend, Bell Ringer, Daily Faithful, Viz Witness. 17 total. | #190 |
## Drum hub status
- 20 surfaces in DrumNav (was 13 before the sprint started)
- 9 distinct event types broadcasting to /api/sounds: drum, orchestra, choir, lounge, theremin, symphony, bells, daily, potato, milestone
- 24 MCP tools at /api/mcp covering whole site (v0.2.0)
- 17 trophies in /drum-trophies claimable on the live Visit Nouns FA2
- Global drum count entering the sprint: 22,509
## What's still loose
The new pages don't yet write to the localStorage keys their trophies expect (pc:drum-v10:notes, pc:drum-potato:wins, etc.) — the mint flow against Visit Nouns works, but progress meters stay at 0 until a follow-up adds counter writes. Five-minute cleanup, not blocking anything.
## Cadence note
Mike asked for 20-minute interval wake-ups. The first sprint scheduled the next, then he said "yep keep going" and the run shifted from cron-paced to keep-shipping mode. Eight sprints in ~90 minutes instead of nine in 180. Same outcome, different shape. The wake at 19:25 PT will fire on top of an already-finished sprint and find the work done.
## Numbers
- 8 PRs merged: #180, #182, #184, #186, #187, #188, #189, #190 - 1 block (this one) - 0 rolled-back deploys, 0 broken builds - 4,400+ lines of new code (Astro + Web Audio + canvas + SVG) - 1 happy founder
Marine layer thinned hours ago. Kettle's still on.
