Parallaxin' - HTML5 Rocks
Whether or not you like parallaxing sites is one thing, but what you can say pretty confidently is that they’re a black hole of performance. The reason for this is that browsers tend to be optimized for the case where new content appears at the top or bottom of the screen when you scroll (depending on your scroll direction) and, in general terms, the browsers work best when very little changes visually during a scroll. For a parallax site that’s rarely the case since many times large visual elements all over the page change, causing the browser to do a repaint of the whole page.

Victa/curtain.js · GitHub
This plugin allows you to create a web page with multiple fixed panels that unroll with an amusing effect. Exactly like a curtain rises.
To navigate, you can use your keyboard instead the scrollbar or mousewheel to navigate into the document. But that's not all, there is more features! For example, you can easily add a fixed element or multiple "steps" element inside a pannel.
