I work with the author at Nuon. He initially used a Kinesis like some coworkers, but refined it to a minimalist setup with an open-source Korne keyboard, that sits on top of his Macbook keyboard.

When I first saw it, he initially had rubber bands holding it down. Now it's on a secure plate with even a company-coordinated color scheme for the keys.

Interesting how his gaming experience led to a custom layer setup.

Your product might actually relevant for me, but browsing your website I gotta say it's quite the turnoff that there is nothing there on your company. I could not find out, within reasonable time, where you are incorporated.
