I personally have been following the project through the weekly videos he puts up about the various design challenges he's been facing, and how his team has been growing from himself to around 10 people. The growth, scale, and skill seen from Martin has been amazing. The project has gotten to the point that he met with the developers of Fusion 360 because the model had so many parts it almost broke the program[1].
I figured that this video would be interesting to HN because it discusses the project management of such a massive endeavor, and I think the project as a whole might appeal to the hacker/maker side of HN.
