equorne on "Full Page Responsive Slider"

Hey!
I didn't find any easy solution... seems as if I will have to do everything with multiple versions of the same image. However, some days ago I found an article on hongkiat.com that showcases some websites with full-page sliders. It doesn't give solutions, but you may be able to learn from them.
