Use warp with the repeat option.
You can add some variations using the offset and flip variations.
offset shift the pattern by some amount in some direction.
If you repeat along the X axis, you can have an offset along the Y, Z 
and X axis. The 3 can have different amplitudes.

The flip option allow you to mirror the pattern along an axis.
You can flip the 3 axis using different periods.

Combining flip and offset, you can make sure that no two planks are 
identical, and always different from it's neibours.
