I totally enjoy the overall theme of the Engrain Tactile Keyboard but love the textured keys made by just sandblasting a board, which removes the softer wood in between the grain. The keys are then cut, branded and glued to an Apple keyboard. But unfortunately this is just a one-off concept and will likely not be sold retail. You could make your own, though. I might.
