Move a pencil while drawing ?

Hello,

Your work is really great, thank you for this !

Would it be possible to move a pencil (or another object) along the edge of the drawing ?

Or is there a callback or a function that could be used to move a specific object from the start to the end of a path, to simulate a moving pencil with some coordinates (e.g. the path's start/end coordinates) ?

The purpose would be to have a hand writing effect while the SVG paths are appearing one by one
