What happened to the Curve: Extra Objects - Spline Generator?

I am looking for a way to generate random curves or splines from a mesh or volume and found just what I thought I needed in Steven Scott’s video (below).

It used to be part of Blender’s Extra Curves Objects but I can’t find it - does anyone know if it is still available or can suggest any other options?

EDIT:
I have been learning Blender’s Geometry Nodes so let me know if there is a relevant tutorial

Thanks

Steven Scott: Blender Spline Generator - Add Extra Curves Tutorial

The options are now on the add menu

I’m sure there’s ways to do the same with geometry nodes setups but I don’t know any specific tool (or nodegroup) that does the same

Oh nice!

Thanks @julperado. That’s great.

I have learned to distort and scatter things over a surface but nothing to do with generating things from a volume.

Thanks
