It probably isn't much. 3 on 3 is the current norm. However I'm having thoughts that the Blue, Red, and Gree 'lights' at the top, is actually the field configuration. If you look really close at the top three, the blue is cut off on the left, the green on the right, and the red is full circle.
I figure this by saying that the yellow fish and the yellow banana are across each other...the orange fish and the orange eyebrow are across each other, the blue eye and the light blue mark on the fish is across each other.
EDIT: You know how there is a picture of Dave tossing his Red snappers and said "Maybe they are Herring". Well after some research, in 2004 75% of all Red Snapper was actually found out to be labeled incorrectly, for those Red Snapper where a whole different fish...Red Herring...Now All I need to find is a connection.
