"The idea is that a set of rovers move through a
matrix of cells until they encounter a wall, another
rover, or an obstacle. When a rover encounters a
wall, it emits a midi note corresponding to the row
and column, then reverses direction. When a rover
encounters another rover, both rovers are rotated
clockwise. When a rover encounters an obstacle, the
effects of the obstacle are applied to the rover
which could alter its position, its direction, both,
or neither depending on the type of obstacle."
