/*
The Controller works as follows:

              __
             |  | <-UP
              --                  __
                                 |  | <-RISE
       __            __           --
      |  | <-LEFT   |  | <-RIGHT
       --            --
                                 |  | <-FALL
              __                  --
             |  | <-DOWN
              --

where UP, DOWN are changes in Y
		LEFT, RIGHT are changes in X
		and RISE, FALL are changes in Z

Note that DOWN causes Y to increase due
	to the left handed coordinate system
