This is a Geometry Nodes setup for generating and animating voxel-based environments. The system fills a scene with instances that rotate around the Z-axis, automatically scaling on the X and Y axes to prevent overlap as they turn. When gaps appear during this rotation, the node tree dynamically fills them with additional voxels.

A custom node group evaluates spatial conditions, allowing the voxels to smoothly transition in size. Instead of popping into existence, voxels scale and translate along the Z-axis to create a growing or melting visual effect. The creator explicitly provides this file as an educational resource and notes performance limitations due to its multi-frame noise sampling and complete frustum instancing.
