Variables
Just a way for cells or the world to remember things. could help with making stuff like pheromones with ants and basically adds intelligence, maybe it could be a shape that would make something say "if [white][red] => [black][white] add 1 to var 1", so if that action is done, it would add 1 to the first variable. And this variable could also have options, like instead of setting a number, it could set relative coordinates on the board.
Concept art
The function depends on where the triangle marked with a blue outline is facing.
Left: Add
Right: Add X coordinate
Up: Add Y coordinate
Down: Reset to 0
This does require down arrows to be implemented, but I think it's the best I can do.
As for functionality, the octagon shape makes it so that only 256 variables can be stored at once, but that's plenty. The values can be stored in a vector3, with the first two coordinates being X and Y, and the last coordinate being the variable's value.
