I present here a simple program realizing 3D scenes. It uses ray-tracing method. It was used to generate animations of two surfaces, spanned on some curves. In both cases, when the surface is moving it contains all points in 3D space (plus infinity), each exactly once (excluding the boundary, which is on each surface). The first surface is spanned on two circles and has some connections with Hopf fibration (points of one colour on one surface are arranged in circle, all circles are disjoint and every point of S^3 is on some circle). The second surface is spanned on the trefoil knot.
