can anyone suggest a suitable template

Hi there,

I have downloaded wordpress and am trying to sort out a website. I have been browsing the themes and playing around a bit. I also had a look at the showcase and I love the look and feel of this website:

I am assuming that this is a custom theme, but am wondering if anyone can suggest a good theme that I could use as a base to create something with a similar layout and that I can customise with my own header, artwork etc

Thanks in advance!
