Notice the line that goes from the A to the Z... I believe its a reference to the bible.
Just like Apple's logo is an apple with a bite in it, (Just like Adam and Eve eating of the fruit of the tree of good and evil.)
These subtle inferences are a wink and a nod to the occult.
Revelation 22: 13 "I am the Alpha and the Omega, the First and the Last, the Beginning and the End.” (alpha and omega- A and Z)
Isaiah 41:4 "Who has performed and accomplished it, Calling forth the generations from the beginning? 'I, the LORD, am the first, and with the last. I am He.'"
That's one perspective...
