[GreenKeys] Touch screen green keys?

[Jeff G]

See I would take this idea (Arduino) and instead of a touch screen, a
modern black-framed mechanical keyboard with.green keys LOL. I think that
would actually look pretty cool and fit the "physicalness" of a real
teletype. It could potentially be bluetooth as well.

Something like this but more greenish:
