This tutorial is pretty wild: using Blender Simulation Nodes, Seanterelle creates a convincing soap bubble effect. One bubble pushes its way through a bunch of other bubbles, deforming everything as it moves along. The moving bubble also affects the colors of everything it touches. The way it's set up allows for interactive results as well!
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
