Porosity Lens Demonstration

This additive Porosity lens is combined with the 3D maze rotating in space. I had to keep the normals facing away from the camera, so it looks a little bit  odd. There is a custom skybox as well, but you can't see it. 

This Perspective of the 3D grid used to construct the maze shows where the density of geometry lies, and with the structure of the maze itself, any entity inside the maze is eventually trapped in the corner, before being tossed onto the new horizontal plane by the rotation. The spawned particles remain in absolute space, and show that despite apparent progression of the player through the maze, they are still occupying the same position in space.
