About Finger in the Crab Dip

Built for music, motion, and desktop atmosphere.

Reactive by design

Finger in the Crab Dip captures your system audio with permission, reads loudness and frequency content, then drives animated scenes that feel synchronized instead of random.

Multiple visual moods

From calm ambient fields to brighter, more aggressive motion, the same audio pipeline can support different visual styles for different setups.

Clean macOS workflow

Designed around native macOS permissions and rendering, so the experience stays clear about what the app can access and why.

Demo & screenshots

A preview of the experience.

A single looping capture is enough here. When you have a better recording, just replace the file and refresh.
