If, by "homescreens" you mean the desktop, you can change the image by going to System Preferences > Desktop & Screen Saver > Desktop

 

yeah not at all what s/he's looking for.

 

What exactly do you want to change??

 

Actually no need to wait for shapeshifter for something like your example really. It looks nice and is well coordinated, but does not appear to be anything beyond dock replacement, a bunch of icon replacements and a new desktop picture (although it looks like the menu fonts have been changed but I can't really tell. I use a similar dock replacement and some of the same icon replacements myself (see below).

You can change icons easily with free programs like "LiteIcons": http://www.freemacsoft.net/ or they can be changed manually with the Get Info Copy/Paste routine, but LiteIcons is quickest and simplest (and can change some system level icons that the Get Info method can't).

There are a LOT of places to look for icons to use for Macs, but one of the most commonly used sources is Interface Lift: http://interfacelift.com/icons-mac/ and they also have hundreds of desktop pics which can be searched by screen size- a real bonus: http://interfacelift.com/wallpaper_beta/downloads/date/any/

Replacement docks can be found a lot of places too- one is http://www.dockulicious.com/docks/index/page:1/ A neat little app to change docks is http://www.ed-shiro.net/index.php?option=com_content&task=view&id=13&Itemid=35 although there are others.

Anyway there is a lot more that can be modified without a full ShapeShifter theme change, so just wanted to give you some examples to work with!
