Hi again :) What's the best way to create an effect where an object (let's say a square) radiates waves, like a stone thrown into water? This is the best example I found of the effect https://stackoverflow.com/questions/32955459/rings-with-ripple-animation...

Would it be creating another square with thick borders and transparent center (let's call it Frame) + automate it's scale so it'll radiate out? What if I would like to have three such waves visible at a time, each with a lower transparency further from the center square, should I create three such Frames?

Or maybe a trick with 'Ripple Image Directionally? It may have worked, if only the lines would extend and connect to form a square. And if it would die out on the third one instead of extending forever.

My best shot at this attached, but that is very far from what I'm aiming for. Thanks :)
