Summary: 


	I saw an interesting copy protection method on a game for the
C-64 (the game is Elite).. The system is called LensLok.  The game comes with
a little plastic lens contraption.  When the program starts up, it displays
some stuff that looks like garbage on the screen.  When you place the
lens gadget against the screen and look through it, you can clearly see a
two letter code. To run the program, you simply have to key in those two
letters.  The two letters are generated randomly each time the program is
run.
	Its a little bothersome, sort of like using a key-disk, but it's okay
for games.
