You're cheating, Jim 8*)  That thing uses some fancy accelerometers to 
magically magnify the level measurments.  No fair.

The other place where a laser level really shines (UGHH!), is in making 
a straight line, especially in places where a string isn't convenient or 
will get in the way.  The cheap Harbor Freight laser I got has a thingie 
on the end that turns the laser point into a line.  Now, you have to 
work in near darkness, but you can put the laser out in front of the 
plane, have a line go through both wing tips, and measure up-thrust at 
the prop flange and dihedral at each wing root.  All with a ruler and 
all in one shot.  Marvelous inventions.  Just marvelous.
