How to make GNOME apps look like this (link inside) ?

[Amit Uttamchandani <amit.uttam@gmail.com>]

Hello fellow debian users,

I was just looking through the new features of GNOME 2.20 and wow a lot of
amazing new features. But what blew me away was the UI. I don't current use
gnome but I use a lot of GTK apps in DWM. Any one know what theme they are using
here? And also how do they make open office look so good? I am currently using
the theme for foresight.

Thanks,
Amit
