WordPress default theme, TwentyEleven , has a built-in showcase mode that is displaying a set a slides (composed of sticky posts) at the top of a page. This mode can be activated by creating a static page and set its Template page attribute to Showcase Template .
All you have to do is to embed this snippet of code within your home page. It could either be in the static page you use as a showcase template or in a showcase widget. The latter is the exact same method I used earlier that year to customize CSS in WordPress without messing with the original code .
And of course this code is currently live at the front page of that very blog.
