Homebrew PCBs

Recently, I was scavaging a broken terminal concentrator which dates 
from the early 90s.  The front panel was made out of a printed, self 
adhesive plastic sheet that was laminated onto the metal of the 
chassis.  I peeled it off and it looked to be about 10 mils thick.  I 
would bet that the material is printable and it felt a lot like the 
convering material for membrane switches.  Maybe it is available.  I 
bet it could be directly printed on a laser printer.

Also, the panel I peeled off had a bunch of translucent sections for 
LEDs to shine through .  Pretty slick but it was probably a custom 
job.
