Several of you searched for the Deathly Hallows Pendant and arrived at my thoughts on Deathly Hallows Part 1.  Here’s what I wrote:

John thinks the deathly hallows symbol combines the world axis with the all-seeing eye and the mirror.  If that’s true, the easiest way to make a pendant that represents the collision of these three (the cross, nous, and the mirror) is to make a Deathly Hallows pendant where the circle (representing the res. stone) spins on the line (representing the elder wand). In this way, you can spin it to make a globe and, with the help of a strobe light, make an eye.  It’s rather subtle when Harry touches the pendant in the movie, but it moves on an axis! It’s a fabulous little detail, and I think she’s winking at those of us that take the time to analyze the symbol itself – especially you John.

To make that more clear, I’d like to give you a handful of pictures.  Please refer to John Granger’s Deathly Hallows Lectures for his thoughts on the symbol.  I am borrowing from him, assuming his interpretation, and simply pointing to the break-down.

1.  The World Axis  Look at the picture of St. Anthony’s Cross.  Now invert it.  This is the world axis, the intersection of the mundane and divine – of God and Man.  How do we know the pendant’s an axis?  It spins on one!  (Refer to John’s Book for the interpretation).

2.  The All-Seeing Eye

Spin it fast, hit it with a strobe light, then what do we see?  We see a circle with an ellipsis inside, and with  line inside the ellipsis.  Looks like a cat eye.  Pull out a one-dollar bill, flip it over, look at the top of the pyramid and you’ll see it too.

3.  The Mirror Image.

Adjust the center circle of your spinning Hallows pendant, turn it so you can only see the edge of the circle, looking dead on.  What do you see?  Two halves of an equilateral triangle, an isosceles triangle with  mirror-image twin:

If they meant to have the pendant spin, meant to communicate this, then I say “bravo” both to John for the interpretation, and to the writers (and producer J.K. Rowling) for showing her cards in such a playful manner.
