Absolut Vorticity

Because fluid is best when properties are conserved. Every run-of-the-mill fluid gives you mass and momentum conservation, but Absolut Vorticity is a step above the rest. Just lay back and let the world spin around you; let Absolut Vorticity take you to a completely new frame of reference. Or, spin with the world for potentially neverending fun. Absolut Vorticity: well worth the advection.
