GridRotator is a Geometry Nodes setup that generates a morphing, audio-reactive effect by instancing objects on a grid. The default configuration uses rotating capsules and metaballs to create a dancing blob visualization. The scale and rotation speed of the instanced objects are driven by noise textures controlled by audio input.

The node tree allows procedural customization of the number, dimensions, and rotation properties of the instances. Users can swap the default metaballs for any other object to apply the audio-driven scale and rotation transformations. The provided blend file includes detailed node labels and explanatory notes to help users understand and modify the setup.
