The keyboard is the heart of this project, it's designed to be compact, one handed and use muscle memory to allow it to be learned quickly.  It's based off of 2 ideas: Half qwerty and butter stick. 

Half qwerty works by mirroring the keyboard whenever a key is pressed, in this case the space key.  Pressing it causes Q to become P, F to become J, C to become N, etc.  The idea is that you are using the same finger and the same row, just on the opposite hand.  I've been using it for a long time and it is very functional and natural. 

Butter stick keyboards work by minimizing the rows.  All the letters reside on just 3 rows, and we can simulate that on 2 rows if you press the top and bottom row to access the middle:

Cut the butter stick in half, add a 5 way joystick to let you mirror and shift and you have a handy keyboard that technically is qwerty compatible
