I was thinking of a keyboard that has displays on keys, long before Art.Lebedev came out with the Optimus keyboard concept. I didn't think of all the functionality they came up with, I just thought of rearranging/reconfiguring the key layout to suit one's typing style. Well, I don't really regret not implementing it, because I couldn't have done it, and it's not really practical.
