I am trying to animate a shape (let's say a plane) with some geometry nodes alongside a curve. My current setup includes a plane with the following modifiers: the Geometry nodes, an array (fit curve and merge checked) and a curve modifier.

Blender file.

Any ideas on how I can animate the process of extending the curve? I could only find this answer online, but it doesn't work with any mesh.

Here's a crude example of what I mean. I want to be able to animate the extrusion, movement and/or rotation of the curve while the geometry nodes are automatically updating the result.

Just use as geometry input a curve.

Then you can paint the curve like this:
