How to create a ripple like effect on the GUI based on ingame data?

Hi everyone,

I must admit that I'm a total noob when it comes down to script so I really need some help. For my current project I would like to show on the GUI where a sound in the game is coming from by creating a water ripple effect such as this one:

with the center being the source of that sound.

My game is a 3d exploration game where much of the level is invisible. The player can explore the world and when he collides with objects a part of it becomes visible. To give players hints of interesting objects I want a visual representation of the soundeffects they hear. In short if a sound plays and the source of that sound is currently in view of the camera I want a ripple effect to show on the GUI.

Can anyone help me with this?

Thank you very much
