Not EXACTLY what you originally linked in this post, but this video should get you onto the right path.
I would imagine you would tweak some things in this code with the .mousemove lines and the what I would imagine to be the viscosity of the said liquid affecting the canvas that you would be implementing.
I also looked at the article you are looking to implement and there are alot of Three.js resources on codepen.io as well as tympanus.net/codrops/ (which you already know about).
Let me know if you have or do find the exact implementation as I would love to utilize this effect! I will search as well to get that exact effect!
@Matthew_Bozanich Thank You so much for all the info. I was aware about ran’s ripple effect that’s not bad even though I find it a little too artificial to the eyes. It could be a nice solution anyway.
Because I miss knowledge of js in general, I just can’t figure out where I would start to do what I would like to do. I’ll keep searching and trying though
