	Well, how do *you* think they align the things?  They're polarized,
you put current near one end and they all line up (ok, "untwist", whatever,
they're still driven by magnetic force, or else LCD's would require quantum
mechanics).  

	Heck, even if the crystals somehow aren't sensitive to magnetism
there's a whole array of little teeny transistors behind them that certainly
are.  Try taking the back off the display and laying your magnet right on the
actual LCD unit.  That might show something.  In fact, if I can find a nice big
magnet I'll try it on a broken one this weekend.  Probably electrocute myself.

	And what about the backlight?  Bet that doesn't like big magnets...
