Easter-eggs in CSS3 ... and a bit of jQuery

I know it's a bit late, Easter is gone but I'm still digesting tons and tons of casatiello (a delicious neapolitan salt cake) and coding is a good idea to help my stomach.

Ok, let's try to draw an easter-egg just using CSS3 and jQuery.

I need to obtain at least an egg, a ribbon and a cockade; everything has to be resizable with the page.
