Ghosty started as an extension of some experiments I’d been doing with the local Sonos API. Sure, you could build your own custom music playing user experience, but what else?

Ghosty was designed to make any house a haunted house. From the confines of a hidden Raspberry Pi, it picked a random time of the night, chose a random Sonos speaker from the network, played a creepy noise at low volume, and then covered it tracks. It was designed to be run for weeks without detection. Think of it as a high power, low severity prank.

Honestly it worke a bit too well, and I couldn’t keep quiet about it. Good for my colleague’s mental health, I suppose.

Fast Company wrote an article about it.
