That's a fair observation, but if he's just setting up the walls
as big cubes *without bodies attached anyway*, their mass is of
no consequence.

And from an efficiency point of view, although a plane<->object
collision is usually cheaper than a box<->object collision, boxes
scale better when using a hash-space (planes cannot use aabb
optimizations so always invoke one nearness callback each for
every object in the world).
