I saw a simulation of this a while back. Your field of view increases as you
pass through the horizon, until 360+ degrees shrink to a circle directly above
you. As you go further and further into the black hole, the whole universe
above you shrinks to a point. Strictly speaking, though, you can observe
anything in the universe that you could before since you are still traveling
slower than the speed of light. The event horizon is only the point at which
light cones tip past vertical so that even light moving directly outward can no
longer make it. There really isn't anything special to the person passing
through it; it's just the point of no return.

They don't really have to point directly toward the center, do they?. It's only
that NONE of them point outward. If you're inside the event horizon, you still
have an infinite number of choices, but 'out' is not one of them.
