	This one one you don't really need to worry about.  To say the least,
"taint that easy".  The decay time of the CRT phosphors is such that you
couldn't really get much from the composite signal a PEC would collect. 
With the advent of LCD displays there will be even less.

	I wonder of your friend was really working on "light pencils", which
are much simpler and easier to implement.
