New Google Image Search Layout?

So it seems that there is a new layout/design for Google Image Search with an expand function that has rolled out to the UK Google.

Old Google Images (screenshot from http://images.google.com/):

W4r8tv9_medium

Which then goes to the following when you click on an image:

T06baly_medium

But below is the new design from http://images.google.co.uk/:

Vbcsmyz_medium

You will see that the images are larger in that default view but that seems like the only change...

But if you click on an image like we did above, you get the following:

Hlusavr_medium

(And yes, it is animated in that expanded area).
