Building a better keyboard - better keys

A brief comment on better key design. We don't have to be slaves to tradition - or even geeky geometry.
For example,  how about a heart shape?

Part 1 - What is the optimum width and shape?

Finger tip & key spacing

• rounded corners is best
• The key spacing (on a jammer derived from a regular keyboard is too far apart to be ideal, but still useful for learning
•   A round/hex hybrid shape for the keys would be better
  
• Possibly a more complex shape.but we can give it a sexier shape, as long as it interlocks fairly well.

-          Acceleration (brightness) (2^nd differential) would be good to have., although most midi does not support it easily. - piano players plainly use it: to quote an expert "using the flat of the finger gives a brighter sound" presumably the flat finger gives a higher initial acceleration, loading the hammer head with speed, but lowering its effective mass, so it bounces off more quickly.

-          Piano key width or a bit less would be good;  The lower limit would be the computer keyboard spacing

-          Color scheme is useful and fun! It also seems to be increasing my weak sense of perfect pitch.

-          Dimpled/scooped surface might be better; it would help keep one centered.

-      with my current large, flat key, it's easy for the fingers to drift - there's no tactile clues preventing it, until one hits a neighboring key.

 A lot of things become possible if there is a modest community of jammer enthusiasts that specialize somewhat – for instant, one could build PCBs – or know a shop that can build them for the community, and one could build the keys – the ideal would be a plastic mold
