Very cool looking, but there is an ocean of mechanical keyboards already available with the US keyboard layout. I would explore making ISO international versions. That market is underserved. Because I wanted a mechanical keyboard with a CAN/CSA Z243.200-92 layout with Mac modifiers, I had to design my own layout in SVG for a Max Keyboards custom job. Keep in mind, I did not want to design my own, but I had to!
