A projector that keeps the cat entertained — build photo from the creator’s source

What the hardware does

A Raspberry Pi renders animated scenes and sends them over AirPlay to a Samsung Freestyle projector, turning a wall into an interactive-looking play surface for a cat.

How the agent helped

The creator describes Codex helping adapt the AirPlay sender, bridge the rendering pipeline and implement wireless projector controls. The physical projector is the output, not just a video displayed in a browser.

Before you build

Requires adapted AirPlay streaming software and compatible projector controls, not just a video playlist.
