Masonic sign

You often see this sign everywhere in plain site, You only start noticing these when someone has shown or told you. You see it on the dollar bill, t.v shows, movies, cartoons and many other places on the media. Some say it's just a masonic sign and some others say it's a sign to represent the Illuminati, But who knows we won't find out.

My friend wullie drew it on my table quite a while back but I decided to take a picture and make a little blog =D
