From the picture, it looks like a red plate, sandwitched in acrylic with a metal top plate (for decoration, I imagine)
Sadly, it also appears to be just a render. Someone made this in a CAD program, I think.
Sweet layout, though. I especially like the spacebar-row. I think the spacebar looks asymmetrically placed and slightly larger, which is prefect forright-thumbers like me.
If it got made, I'd expect it to only see light in Korea: They make all the custom keyboards, it seems.
