I think I may have it figured out. Putting all 3 things together. T
he light display at the championships, the official picture, and
dave's new hint.
I think its about different terrain on the field.
On the image the background looked ripply, like water. But when I thought about one of
dave's previous posts I thought about ice. That would lead to the blue light on that part of the field.
Then this talk about fire made me think of volcanoes and all the rough terrain around them. That would lead to the red light.
The green light could be one of 2 things depending on what the game may be. I haven't fully made up my mind as to what it may be.
The green light could be for grass, a 3rd, normal part of the field. If this is so then the game, i would guess would be a time trial like we had in the past. 5 robots would be going around. the diamond plate discs could be like slalom gates or obstacles.
My other thought was that the field would just be split in half and the green light would highlight game pieces. The diamond plate discs could be the places where you put the game pieces to score.
I haven't paying much attention to the speculation so please don't get mad if I took your idea. please let me know what you think.
