I saw these guys at Portland Retro Gaming Expo. I played the demo a tiny bit, and while it was interesting in a way... it felt a bit too early to be showing to people. Maybe it was the 3D printed stuff that made it amateurish.

That said, if I am recalling correctly, the was open-source (oh I found the site and it is) so maybe that whole booth was to demonstrate how someone could build their own unit.
