Cool.  It looks a little sharper at the edges than I would have expected.  I
read that book "Black Holes and Time Warps" or something by Kip Thorne, but
I don't remember exactly how things LOOK as they fall in.  It would be an
interesting patch though to actually simulate it.  No idea how it's done,
but it looks like raytracing has been applied to both special and general
relativity.  A cool gif of a black hole on the page.
