#1 Hypnotic signs
Pure, unadulterated noise alone may not be as effective as a well thought out sequence which is scientifically designed to create a distraction.

One look at these crafty signs and you'll realize that a lot of thought and effort goes into creating a distraction. Napoleon could have used some of these bright minds to create distractions during wars.

If eyes could hypnotize, this one would definitely take the cake.
