A hidden Triforce in the Google Earth logo... you do know of the Triforce... don't you?
If you would seek the sacred triangle, listen well. The resting place of the sacred triangle, the Sacred Realm, is a mirror that reflects what is in the heart, the heart of one who enters it. If an evil heart, the Realm will become full of evil; if pure, the Realm will become a paradise.
The Triforce...the sacred triangle... it is a balance that weighs the three forces:
Power, Wisdom, and Courage.
If the heart of the one who holds the sacred triangle has all three forces in balance, that one will gain the True Force to govern all. But if that one's heart is not in balance, the Triforce will separate into three parts:
Power, Wisdom, and Courage.
Only one part will remain for the one who touched the Triforce...the part representing the force that one most believes in. If that one seeks the True Force, that one must acquire the two lost parts. Those two parts with be held within the ones chosen by destiny, who will bear the Triforce mark on the back of their hands.-The Book of Mudora
The Triforce is a triangular relic which features throughout the series as a nearly-omnipotent sacred item representing the essences of the Golden Goddesses. It is made up of three smaller triangles known as the Triforce of Wisdom, Triforce of Power and Triforce of Courage. Each of these embody the essence of their respective goddess, and bestow certain boons on their bearers. As shown in The Legend of Zelda and The Wind Waker, each piece can be further subdivided, though they become powerless in this state.
In most of its appearances, the Triforce or its pieces manifest as a crest on the hands of their bearers. These crests resonate when near each other, and the Triforce pieces can emerge from their bearers.
When united, the Triforce allows one who touches it to make a wish that lasts until they die or the wish is fulfilled. However, if the one who finds it does not possess a balance of the three virtues it represents, the pieces split into its three components and the finder is left with the one which represents the characteristic they value most; the other two pieces do likewise with two other characters "chosen by destiny".
