Escher Falls  embeds a fluid simulation inside one of a classic illusion.
“Science and art sometimes can touch one another, like two pieces of the jigsaw puzzle which is our human life, and that contact may be made across the borderline between the two respective domains.” - M. C. Escher
In Color Loom , Sculpted forces pull a fluid sim into a weaving pattern. Very challenging sim with many many iterations, some too chaotic, some not chaotic enough. This one was all about finding the goldilocks zone between drag, viscosity, suction, orbit, noise amplitudes and more.
Pond in the Drop  uses a high surface tension water droplet simulation as a container for a much larger fluid simulation, the colors of which are mixed as the droplets merge...
