This is not directly specific to your post Rad, but I am sharing this since I feel it is insightful information about the transit of Venus.
Whats most amazing about Venus is the pentagram it makes in its orbit over a 8 year period. This pentagram as I understand it is marked by 5 retrograde conjunctions with the Sun which naturally occurs within an 8 year cycle. All of the 5 conjunctions naturally occur within the orb of a bi-quintile from one transit to the next, ending the 5th conjunction very close to where the cycle began with the first - thus creating a pentagram.
Here's a diagram of that created by Adam Gainsburg: If you start in 2004, this coming up conjunction in 2012 marks the end of an 8 year Venus cycle.http://soulsign.com/wp-content/files/mars-venus-training/Venus-Journeys-3D.pdf
And a video depicting the phenomena of the pentagram as created by the retorgradation of Venus along with it's conjunction with the Sun.http://www.youtube.com/watch?v=4nI3Ky8mhj8
