Try The Demo! - http://gimppimp.tk/demos/freeweblayout/
Again created in Gimp 2.6.11 About an hour and a half maybe longer for designing, and coding.
When/If you download the zip file once you open it you'll see two folders. One saying PhotoShop Project which contains the photoshop .psd file so if you wanna edit the web layout you can. The other folder is called Web Layout which holds the codes, and images saved to make the web layout. So everything is already done for you all you need to do is change the content text to whatever you want.
When the web layout loads you'll see just the header for navigation once you click that the main navigation will all slide down in a nice animation. Once you click home, about, etc: Thoughs extra divs will display showing you what's there. Also done in a nice smooth animation.
Coded in HTML, CSS, CSS3, and JQuery.
