Quoted from DCFAN:
The first 6 are purely decorative. I am not sure why they decided to put lights/inserts under those. They could have merely been art on the wood. I guess it was an art choice in that they decided they wanted the lights to be in a spiral pattern the same as the art (like the beginning of the yellow brick road in the movie starts in a spiral). The #1 insert is the first yellow brick road insert for identifying how many of the shots you have made.
Awesome thanks for the info. Guessing the yellow brick road is dimly lit and get brighter as u progress?
