"Gooey" effect recreation

Hi guys!

This project was done this three.js

How can I recreate this kind of “gooey” effect?
Im little bit familiar with JS, but never used three.js.
Could you guide me some direction needed for achieving this?

Thanks in advance.

As a starting point, use this video from @akella: #3 ALL YOUR HTML, Canvas Jelly Effect - YouTube

PS I made this thing, just copypasting most of the code for point movement from the example in the video: Spring - JSFiddle - Code Playground
