You have it all explained right here in front of you. Three hexagons (666), the name brand of the ball is “hex” and the series is “Evo” as in evolution. If I only saw one set of three hexagons on a product, I would not have given it much thought. But there are scores of examples on this website of grouping 3 hex’s together. Your mind subconsciously associates the hexagon with the number 6, and without thinking of it on a rational conscious level, your subconscious mind is processing the information that is subtly represented on this product. Hence, what used to be called “subliminal advertising” is now referred to as “perception without awareness.”
