There are a few things that I could call this - but essentially it's using the Push Along Vector behaviour to make things deform. I show you how you can separate the X and Y for a different look too. It is a vector fish eye effect in Cavalry App. I'm just writing that to help the algorithm! In this tute it is just the deformation - not the grid animation (inspired by illo) You can see how that is done in a tutorial I did a month ago called: benko basics | Rectangle Shape I use duoKo in this too - you can check it out at
