Blender-FLIP-Fluids
The FLIP Fluids addon is a tool that helps you set up, run, and render high quality liquid fluid effects all within Blender, the free and open source 3D creation suite.
The addon you're referring to is already a polished product: https://github.com/rlguy/Blender-FLIP-Fluids/wiki/Mixbox-Ins...
It works as a kind of 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!

aphros
Finite volume solver for incompressible multiphase flows with surface tension. Foaming flows in complex geometries.

Fltkhs [1] was the best ever experience I've had while doing small/auxiliary GUI utilities. Now using NWG [2] for that (UI forms examples [3]) and it is so much less elegant so much more verbose than Fltkhs. Resulting lean EXEs without any bundled runtime are nice though.
