Using 3D Planes as "Child Keys" you can intersect them to generate a unique point in 3D space. This point is then used as the encryption key for a simple XOR encryption.
Since people generally find encryption boring. I wanted to add "Hollywood" style graphics. The 3D graphics are rendering the actual encryption keys. Some animated textures and camera animations are added to spice things up.
