We are making April 1st prank in our office, and wanted to flip our corporate website upside down for several hours tomorrow :)

My patch works everywhere but not in IE..

Answer 1

EDIT: This doesn't work.

Try

body {
     -moz-transform: rotate(180deg);  
       -o-transform: rotate(180deg);  
  -webkit-transform: rotate(180deg);  
      -ms-transform: rotate(180deg);  
          transform: rotate(180deg);  
             filter: progid:DXImageTransform.Microsoft.Matrix( 
                     M11=-1, M12=-1.2246063538223773e-16, M21=1.2246063538223773e-16, M22=-1, sizingMethod='auto expand');
               zoom: 1;
}
