A Geometry Nodes setup that applies a stem and peel spiral effect to any input curve. The system modifies the base curve into an unfolding spiral, allowing users to control the resulting shape, length, resolution, and bevel. The generated geometry includes a UV map exposed as an attribute, which can be accessed within the Shader Editor for custom texturing.

Designed as an educational resource and functional starting point, the node tree is organized with visible logic and text explanations. The nodes are left expanded rather than being consolidated into a single group, making the underlying concepts easier to dissect and modify.
