There are a billion holes on this thing, because I wanted it to be able to be mounted on either the left or right side and support many possible configurations.
[x][x][x] [ xx ][x] [x][ xx ] [x][ xx ]
[x][x][x] [ xx ][x] [x][ xx ] [ xx ][x]
[x][x][x] [ xx ][x] [x][ xx ] [x][ xx ]

[size=78%]Why you would do that last one is beyond me, but it's theoretically possible.[/size]So the other idea which I didn't quite get to was to add the drills hole guides and silkscreen so that the board could be trimmed down into a 1x5 or 2x5 configruation allowing additional possibilities:
[x][x] [ xx ] [x][x] [x]
[x][x] [ xx ] [ xx ] [x]
[x][x] [ xx ] [x][x] [x]
[x][x] [ xx ] [ xx ] [x]
[x][x] [ xx ] [x][x] [x]
I was intending that this one board could be cut down to 2 * 1x5 strips, which would have pads on both edges, so both of the strips could be used.
Things I never got to:
-support for stabilizers
-adding helpful breakaway drill holes
-testing it or any other sort of careful review
I am unlikely to get back to it, but I can post the files here if you want to play with it.
Also, relevant to this topic... I've been using this teensy powered thing I made a few years ago. Now, I never liked WASD, and the arrow cluster was too far away from things, so I played on the numpad.

I almost never use the ones with the 'F' keys on the right, and the gap between the 'esc' row and the rest was someplace to slot the teensy. I find the pinky keys to be a bit awkward so for the gen 2 I introduced a column stagger... only problem is I killed my teensy and don't want to buy a new one :s, so I still haven't really used it.

Instead I made a design for gen3 which has the atmega on board
