benzene666 keyboard
This benzene666 keyboard, has a hexagonal key arrangement.
Total number of keys: 76.
Very scifi, but does hexagonal key arrangement really work?
Basically, it moves up the middle finger column by half key and moves down the pinky by half key .
Moving the middle finger column by almost half key can be seen in Kyria Keyboard and Bloomer Keyboard
Moving down the pinky column by half key can be seen in Keyboardio and Diverge 3 [see Diverge Keyboard]
