What theme is this?

How can I change the default Ubuntu top panel to look like this (http://www.gnome.org/start/2.18/notes/en/figures/figure-desktop-big.png).

Do you know what theme this is and where I can find it?

Someone correct me if I'm wrong, but it looks like the default Gnome theme.

Guess you're right. Looks like a slightly customized GNOME desktop. Nothing special though.
