So we're not seeing, in this angle, we're not seeing the bottom of it. And if you were to just orient yourself, the axes in this case look like this. So this is the y-axis, and then the x-axis goes right inside of this thing, and then pops out the other side. And if this thing was transparent, then you could see the back side. It would look something like that. The x-axis, if you could see through it, would pop the base right over there, would go right through the base right over there, and then come out on the other side. So this is one orientation for the same thing.
