what it is

LlizardOS is a custom operating system designed for the Spotify Car Thing hardware. When Spotify discontinued the device, the small touchscreen became an orphan - a screen without purpose.

This gives it new purpose: a dedicated media display that connects to your phone via Bluetooth, showing what's playing, providing tactile controls, and staying out of the way until needed. Cold-blooded efficiency.

the ecosystem

LlizardOS doesn't work alone. Llizard is the raylib GUI host that renders the interface and loads salamander plugins. Mercury is the BLE daemon that connects to Janus on your phone. Together they form a complete media display system.
