I can think of no less than a dozen applications for this Fullscreen Slit Slider demo. Not only is it impressive to experience, it's actually easy to implement as well. Aside from the inspiration the demo itself provides it also made me familiar with the following, which I believe will now be incredibly common tools in my proverbial Code Toolbox:

• jQuery Cond - chainable "if-then-else" jQuery statements
• jQuery Transit - an alternative to $.animate() that uses CSS3 transformations in much more pleasing way.
