Mootools style switcher with cookie support

We need a small javascript function created for switch between stylesheets and set width of a layout with cookie support
to remember visitors settings.

To swith between width of the layout, a nice transition effect as seen here(top right you have three buttons,presss one
of them to see it in action):http://demo.yootheme.com/apr07/ , and without page reload.

To change color scheme, take a look at this here:http://www.purestructure.com/websites-design.aspx
You can see three "icons" to right of the menu bar, press icon to right to slide down a area where you can press 4 different icons
to change style. also see the style changes without reload the page.

The cookie support should be in php and be as a function in php.

If you should need more information please let us know. For the winning bid the files this should work within will be delivered. And a fully working demo should be shown.


NOTE: You do not need to do any graphic work.
