The concept is a simple one and honetly you will feel a little stupid after you get it... However,
that being said do not fall into the trap of not giving it the time needed due to its simplistic

simple to prepare and highly effective. The matrix routine at the end is a really nnice bonus and is
why I gave it 4 instead of 3 stars.
