Movable blocks (images and gifs)

Hey!

Very interested in implementing the following effect on some of my galleries:

https://biancasciuto.com/

It would be nice to have some of my project pages able to move the image blocks, anyone has info on how this can be achieved?

Even with code and all that.

I only found this: https://www.squarestylist.com/shop/p/movable-blocks

But seems to not work or is not updated.

Let me know!
