Below is a 1st Degree Masonic Tracing Board. Notice the checker floor of black and white squares. It's the board (and life) of ordinary people who are constantly fighting on the good/bad, day/night, yin/yang. The goal as a mason is to move up beyond the melee of the common man

Notice the Cop's hat. His head is covered by a black hat and his head is wrapped in the checkered pattern.

Also... The graduate of college has his or her head under a black square. The higher "educators" have an octagon. The octagon is symbolic for the cube.

So this picture that you posted as a meme is worth 10,000 words!
