A split 4 x 7 vertically staggered keys and 4 thumb keys keyboard.  
An idea is inspired from [crkbd](https://github.com/foostan/crkbd), [Lily58](https://github.com/kata0510/Lily58), [Ergo42](https://github.com/Biacco42/Ergo42) and [Helix](https://github.com/MakotoKurauchi/helix).  
Pinky4 is designed for PoC.
