I have a PDF file that you can print, cut out, and tape together the tetrahedron of the four ternary compositions we're printing. I created it to help show others what we are doing. It also clearly shows that we are only looking at compositions on the faces of the tetrahedron. The next step will be to find a way to explore the interior i.e. a quaternary space.

If you see places for improvement let me know.

Cheers,
Casey
