"What appears to be a Russian design company has on their website a keyboard in which the keys are using OLED to display what function the keys represent. The product is Art. Lebedev Studio's Optimus Keyboard. The uses of this could be amazing. They have pictures of layouts for Photoshop and Quake, as well as a QWERTY and Russian. Here's hoping that this will make it to a production model and not just a design model."
