iBleeedorange posted this pretty GIF that shows the 5-fold pattern traced out by an imaginary line between the Earth and Venus.
Sunsunsun made an audio representation of the orbital relationship between Earth and Venus:
The left side is Venus and the right side is Earth. It takes about 1:36 to synch up, but it almost synchs up (the planets would be directly opposite each other) around 46 seconds in. Each 8 bars represents an orbit around the sun. Do not listen to this without headphones, it makes no sense without being able to separate them.
Make you own "dances of the planets" here.
