This shows the pattern traced by a line directly between the Earth and Venus as they orbit the sun. This pattern is pretty ancient, for example discussed in the book Quadrivum about the old academic relationships between art and science. This type of pattern may be helpful to appreciate the concept of Orbital Resonance in a planetary system.

@Xen - can you post the above as a remix? it seems to have errors - is it a parallax version?
