From the utube page:
I've recently discovered an animation that was rendered using the measured redshift of all 10,000 galaxies in the Hubble Ultra Deep Field image.Open it up to full screen and enjoy. Wow.
I've written a short script that leads you through a quick history of both deep field images and this video ends with a fly-through of the Ultra Deep Field.
Every galaxy in the image is in its proper distance as viewed from the telescope line of sight.
As if this image wasn't amazing enough.
