This is a basic study in green, in HTML5. I've decided to use a collection of
section elements housed within an
article, but I could have used a generic container (i.e. a
div). As long as the outer container (in this case
article) holds the background image and is fixed, then you can get a scrollable background!
It's all rounded corners, and an inset box-shadow to create a three-dimensional effect. It perhaps is not as good as a drawing - but it's quicker.
You could use this for a kiosk or information terminal; and bearing in mind that you don't only have to scroll horizontally, a very creative person could create an accessible web-comic where the reader was guided to each frame, with the art rendered in SVG, or text with :content generated images.
