How to Create Fractal Tetrahedron from squares?

Hi Everyone,

I’ve been doing a little research on fractal tetrahedrons and how to create them in grasshopper, but can’t seem to find any tutorials to create square based versions of them like in the image attached, the whole portfolio link is…[https://issuu.com/emilylucchesi/docs/algorithmic_sketchbook]

I have no idea where to start with creating this, so i thought i’d quickly ask here if anyone knew how to begin, otherwise i’m going to try follow this tutorial [https://www.youtube.com/watch?v=PpcOP_38fQc] and try substitute with cubes. Thanks!
