Kozai resonance

2004 XR190 y (145452) 2005 RN43 have unusual orbits because, in spite of its low excentrity (almost circular orbits), they have high inclination over the ecliptic plane. 

In celestial mechanics, the Kozai mechanism, or the Lidov–Kozai mechanism, causes a periodic exchange between the inclination and eccentricity of an orbit. The effect was described in 1961 by the Soviet specialist in space dynamics Michael Lidov while analysing the orbits of artificial and natural satellites of planets, and in 1962 by the Japanese astronomer Yoshihide Kozai while analyzing the orbits of the asteroids. Since then this effect has been found to be an important factor shaping the orbits of irregular satellites of the planets, trans-Neptunian objects, and a few extrasolar planets and multiple star systems.

Venus-Earth combination

The book "Fractals: The Patterns of Chaos: Discovering a New Aesthetic of Art, Science, and Nature" (John Briggs, 1992) is illustrated with fractal images directly take from nature.

 
The movie "When a Strager Calls" (2006) is located in an enormous house in the woods near a lake. The inside of the house is ornamented like a zen garden.
