 I really want to do it in discrete logic.  Call me crazy, enough 
people
  do as it is... 
Sounds good to me...
  Actually, I'd probably do it in 40xx CMOS, simply
because I don't 
want
  to have a +5V supply the size of a MIG welder lying
around. 
:-)
  What indeed...  Now, Maplin do some nice 13mm LEDs,
how big do you 
think
  we could make a panel?  How about the 3" LED
clusters they use as 
tail
  lights on buses round here?  Make a PDP-8 6'
across, like the giant
 MS-20 that Korg made for demo tours in the 1970s? 
But then you'll need the MIG welder again :-)
