And Art Lebedev also introduced an Optimus Maximus keyboard, where each individual key has a tiny display -- yet every key is still a physical key -- back in like 2008 at CES -- 12 years ago -- with smaller prototypes and announcements for several years prior to that (they've even got vapourware awards because production has initially been delayed after a lot of initial attention -- it's finally hit the shelves in 2008). https://www.youtube.com/watch?v=IJ5rX6WpxTk https://www.youtube.com/watch?v=IJ5rX6WpxTk https://en.wikipedia.org/wiki/Optimus_Maximus_keyboard https://en.wikipedia.org/wiki/Optimus_Maximus_keyboard https://www.artlebedev.com/optimus/maximus/ https://www.artlebedev.com/optimus/maximus/ They were pretty expensive, and looks like they've all been sold-out and are no longer manufactured.
