If you follow the github link (github.com/codybloemhard/eliza) you will find a picture of the matrix! I really like the upside down mods for space bars. It depends a bit on how you angle your hands when you type, but if I put the ‘space bar’ modifiers in their regular orientation, the edge will dig into my thumb. One thing I would do differently is the position of the screws. Two of the screws are right where my thumb comes down on the board when I press down the space bars. This was slightly irritating and I had to get used to it.
