Ubuntu Desktop

[Bob Bond <bob bond pathwaysoftware com>]

Hi,

I wonder if anyone can help me? I am new to Ubuntu/Gnome and I'm 
struggling to do something that I suspect is very simple.

My standard distribution of Ubuntu has Gnome included and the desktop 
appears as attached.

However, I would prefer a much cleaner desktop, more akin to Mac OS X. I 
have seen desktops that look like the attached (Gnome-Desktop) but cant 
find a way to create that look.

Please can someone help?

Regards,

Bob
