OLED Apple Keyboard

A couple weeks ago, we reported the release of Optimus keyboard, the keys of which are equipped with OLED screens. Chinese people at IKeyInfinity Corporation hacked a regular Apple keyboard with such OLED screens. However, it works on Windows. This is more related to advanced research than DIY modification, but still, such a "bidouillle" deserves congratulations!
