Album cover as ambient object
Not metadata. Not a notification. A glowing artifact on your shelf that breathes with the music.
Peepwho turns your Sonos playback into full-frame album art on a 64×64 RGB matrix. Album cover as ambient object — not just metadata.

// the story
In 2022, I shot a quick prototype: a $15 Raspberry Pi could already show what was playing on any TV. Cute trick. But the idea kept burning — what if the album cover wasn't a thumbnail, but the object itself?
Peepwho is the answer. A pixelized LED slab that lives on your shelf, glowing with whatever's spinning right now on Sonos. When the music stops, it idles into ambient color fields. When it starts again, the cover slams back to life.

// the stack
From low-level HUB75 timing to App Store packaging. Every layer engineered like it's going into a stranger's living room — because it is.
01 · concept
Not metadata. Not a notification. A glowing artifact on your shelf that breathes with the music.
02 · silicon
Low-level HUB75 driving, color-order calibration, deterministic real-time rendering, on-device credential protection, recovery flows.
03 · platform
Normalizes Sonos state + artwork into a display-ready API. Auth, allowlist, rate limiting, safe media handling.
04 · distribution
Packaged for the Home Assistant repository flow with versioned releases, install docs, and real ops constraints handled.
// 64 × 64 = 4,096 pixels
No LCD. No simulation. 4,096 individually addressable LEDs pumping out actual rainbow goodness, calibrated per-panel for color accuracy that does justice to a Hipgnosis cover.
// waitlist
Pick how you want it: as a Home Assistant add-on, on your TV, or as a 10″ living album cover that lives on your shelf.
// ship it
