Computer Magic is usually what I call things that I make that would have an overly technical explanation into how they're made.
But just in case someone is interested. This was created in Cinema 4D using the xParticles plugin. A 3D head model was used as the source for the emission of the particles and all of the particles were added to a xpDomain object which is a voxel grid. A second emitter also using the head as a source emits temperature into the voxel grid increasing the temperature attribute on the first set of particles. Then the temperature attribute was mapped to the particles radii via a curve that remaps the values so that they give this wave effect. Lastly the particles color was also mapped to the temperature value via a gradient.
In other words...Computer Magic.
Thanks for looking!
