Hi* GH.
I don't like backlit keyboards, but I am human so I think lights are cool. Rather than having a full keyboard's worth of LEDs on at once, briefly turning on the LED corresponding to the key pressed might make for an interesting typing experience. The LED would be on only when the key was pressed. I think complex key combinations would be very satisfying.
I'm wondering if anyone has done this or has opinions about whether it's possible/easy to do. To my surprise, forum searches didn't return anything relevant.
I assume this would be almost trivial, but I haven't built a keyboard (yet! (holding out for GH60)) so don't have any experience to back my assumption. Regardless: there are keyboards that have LEDs at every switch that turn on/off together; there are keyboards that have individual LEDs turn on/off on keypress; so it seems possible.
