I went through several sections of the article and I am still none the wiser about what this project is. Is it a software emulator? If so, on which platforms does it run? How do I download it? Or is it a hardware device? The article jumps right into the middle of things and bombards the reader with jargon without explaining anything for the HN user like me, who just stumbled upon the link on the home page and is trying to understand the project.
