Oh reminds me of the Optimus keyboard. It seemed like an ambitious idea a decade ago, each key was supposed to be an individual display. Afaik, it never made it into production.

https://www.artlebedev.com/optimus/ - the website doesn't work properly, so I'm guessing you still can't buy one?

I own an optimus popularis. They only ever sold small quantities. Cool idea but not worth it.
