    As a proof-of-concept, this would be perfectly valid and reasonably easy to
    implement. As a product however, I don't think too many people would go for
    it. The group of people who are interested in zero key-travel keyboards (be
    they projection, sensor keys, reflection) is pretty finite and I would
    wonder if there is any significant overlap with the group of people who
    would want dynamic keycaps.

    As an aside, some years ago I saw an old 16mm film from Bell Labs(?) that
    showed projection on a glass surface for a complex switch operator
    Also, a former coworker of an acquaintance of mine is working on a
    laser-based keyboard that uses beam interruption as its key switch. His
    motivation is an extreme case of RSI.
