Diving in a reflective tetrahedron

The interior of a regular tetrahedron whose faces are mirrors partially colored red, green, blue and white: every apparent line is some (possibly high order) reflection of the edges of the tetrahedron. The viewpoint also follows a light ray, i.e., a straight line bouncing on the reflective sides of the tetrahedron, giving the impression that it goes "through" them, as if exploring a very large space with a strange geometry. Each brusque change in color corresponds to the viewpoint reflecting on one of the sides.
