A procedural spiral galaxy generator built with Geometry Nodes. The system distributes points and spherically shifts them based on distance gradients to form spiral arms. An additional setup simulates the gravitational distortion of a visiting black hole.

The files include multiple iterations ranging from basic implementations to more advanced configurations. The node trees are structured for educational purposes, focusing on readability and demonstrating the core concepts step-by-step rather than hiding logic inside exposed node groups. Parameters like star count, density, and rotation speed can be customized within the node tree.
