It's sooo humbling to see an image like that.
One thing I'm waiting for is when they start using the Light Field
technology
to take these images. When I zoom in, it's not long until the image starts
getting blurry because even though the image is what- 17,000 x 11,000?
That's 2 dimensions. What if they used Light Field tech to where we could
keep zooming in and everything is still in focus? I don't really know if I'm
understanding this LF technology accurately, but it's very very
interesting.

That Lytro is definitely a fascinating find. But look at what you're
asking...
The Lytro camera offers a way to choose a focus between a near object
and its background *after* you've shot the photograph. So we're
talking at most a two- or three-foot focus vs. a few hundred feet
(background), which yes, is a fairly great technological feat.
However, with images such as the UDF, those background galaxies are
quite a bit more than a few hundred feet from the foreground galaxies,
maybe a few hundred _light years_ or more. So 4HEAD ol' buddy? I
wouldn't get my hopes up.
