How to do this image mouse hover?

Hey guys,
I recently saw an animation on an website that I would like to replicate. It’s the image mouse hover on this website Innovative Production Company in Stockholm - Framebrains at the “Our Creations” section.

Any idea how to do it or how this animation is called?

Thanks,
Maxi

hi @Schmitti_htnh here is a very simple principle example I have now created based on styles I have read from website you have posted. You can take it as starting point and customise it to your needs.
