Its essentially and undulating mesh that is fixed at the centre almost like cloth to flag pole whilst the outer edges ripple. The animation has to be a dot arrangement yet despite trying everything from xparticles to atom array and cloners I can't quite hit it.
Any ideas? link below of what it is i'm trying to emulate, it's the stuff further down the page that's quite colourful and has in this case been created in unity;
By using the sound effector you can move points up and down to create ripples effects.
Maybe by using some Animated noises into the sound effector should be a good idea.
You can clone rings by using the cloner With 0,0,0, into the size and step effector for moving rings
