It works as a kind of experimental extension supplied with the paid FLIP Fluids addon. Note that the fluid solver built into Blender is also an implementation of FLIP, but "FLIP Fluids" is a separate product. I've played with fluid simulation in Blender quite a bit. The bundled FLIP is very limited, FLIP Fluids is great, and the color mixing is amazing!
