You warp it by the normal curve so that 'normal' data will produce a
streight line.
That's very clever, but it's not a very sensitive test: for
y=rand(100,1)+rand(100,1)
nt(y) returns 0.996 (this holds even when one uses 10000 points for better
stats).
The distribution of rand+rand is triangular, so noone would mistake it for a
gaussian.
