This is similar to an idea I had many years ago, but goes to a much much higher level. I wanted to make a joystick/incremental encoder/pushbutton by placing an encoder pcb over 4 force sensors, so that one could either act on the encoder single button, or rotate the knob, or move it in different directions without rotating it; a RGB LED ring would give an indication of the values by emulating multi digit precision. Mechanical difficulties and lack of time prevented me from even starting it. This one however is cool beyond any imagination, kudos to the author for releasing it as FOSS&H; I hope to see it produced some day, possibly also a cheaper version (LED ring instead of screen, no motor, etc) since the BOM cost alone could be discouraging.
