Hi.
This ought to be moved to the "Beginner's" section.
But as long as we are here, check out the "move" command in the dictionary, taking special notice of how a control can move along the points of a graphic.
So any path can be characterized as a list of points, and this can be generated in any number of ways: by the user dragging something, by tracking the cursor, some action under script control, or, as I said above, tracking an existing graphic.
Now the fun part. The points of a graphic are just a property of that graphic. That means that even if you hide it, a control will still move along its points.
