Hi John, So.. What I done was to imagine a point of the small plant behind the large one. I then marked that with annotate (hold down "d" and draw a dot) then played with the f curves of xyz scale and z translate every 10th frame so that the dot you drew stays on the "focus" point. the aim is to keep the second pot on the dot. I have put a picture of how my fcurves look like on my community tab. the upper curve is XYZ scale and lower is z translation
