I always wondered what it was - then the other day I realized it was a excerpted lines from Alfred Lord Tennyson's poem "In Memorian A.H.H."

I thought that was pretty neat...

that's was awesome!

everytime i hear that voice, that magic text, i can't tell what i feel...!

O earth, what changes hast thou seen!
There where the long street roars, hath been
The stillness of the central sea.


The hills are shadows, and they flow
From form to form, and nothing stands;
They melt like mist, the solid lands,
Like clouds they shape themselves and go.
