Assume a porous solid contains a network of small channels, which are all open or closed with a certain probability. Depending on this probability, will a fluid be able to flow through the solid?

Ehrenfest’s model.

This music video is a pure fractal animation made for Flinch, who is an electronic musician from North America. It is made in one of the well-known and still-under-evolution fractal programs Mandelbulb3D, except for minor post-render adjustments in Adobe Premiere. The animation is altogether a combination of 4 basic fractal formulas and what is seen during the 5:45 of the play is the result of variations in the constructing numeric variables defining these formulas or those controlling environmental phenomena like colors, lights, etc.
