Back in late 2022 I developed a GIMP plugin called GEGL Polygons; found here -
https://github.com/LinuxBeaver/GEGL_Polygons - however if its code is slightly tweaked it becomes "GEGL rock surface texture" a new plugin that will be released soon.
As seen here they are very similar (pics attached of Polygons and Rock Surface Texture)

Notice how the only differences are
1. Cell Noise has different parameters
2. Emboss has different parameters
3. Color is a different color
4. In rock surface texture - gegl:Mantiuk06 is inside a normal alpha locked blend mode at 20% opacity
Other then that the filters are ALMOST EXACTLY THE SAME which means it would be easy for me to make Polygons and Rock Surface Texture one plugin that has a drop down list to select one or the other. But from a users perspective it would be confusing. But the code is so similar that it would be easier on me to do this.
