I created a particle morph, but how can I make the voronoi-like pieces follow it?

[tako32]

I watched Junichiro Horikawa’s lecture and created particle morph. 

And while searching to find a way to move the object’s pieces in sync with the particle’s movement, I came across the following article.

 

 

However, the attached file has expired and cannot be downloaded, so I cannot implement the content written in the comments.

Even if I don’t have to follow the particle’s movement exactly, could you tell me how to perform Voronoi morphing from A to object B?

Thank you for reading it.
