    Hmmmm...  kinda neat if you're programming in Octal all the time...
 then the layout gets almost, dare I use the word: 'ergonomic'.....? 
 
 Aha!  That makes perfect sense.  Good eye. 
 
Well, it might if either the 4/3/2/1 and the 5/6/7/0 columns were in the
same order.  ... but ... what's that 0 doing "after" the 7?  In short,
I don't see it is vaguely appropriate for octal, either :)
