Hmmm.... I notice that the chordite version on the front page could
be implemented using the poker chip indexing system (mentioned
somewhere on chordite.com, but I can't find it right now). I also
notice that the keys themselves could be manufactured symmetrically,
so there's actually only one piece of plastic for both distal and
middle keys. It goes together upwards for distal and downwards for
the middle key. You could make a prototype using poker chips with
microswitches glued between them. Has anybody tried that?
