Da Vinci Code Cubes

The Da Vinci Code Cubes are cubes on the multiplayer level Heretic in Halo 3. They are under the Grav-Lifts in the center of the map and the Grav-Lifts all over the map.

How to see Them
To see these cubes, you have to go to the center of the map in Forge, and build a supply case, and then put barricades on top of it. Now just perform the Forge Turret Glitch. Look around and you will see a cube that has the same design as the Easter Eggs on Sandtrap and Sandbox.
