What are some cool JQuery CSS3 effects like Google s Barrel Roll

Question

For those of you who do not know how the "Barrel roll" is done, here's the code:

<style>
.barrel_roll {
    -webkit-transition: -webkit-transform 4s ease;
    -webkit-transform: rotate(360deg);
    -moz-transition: -moz-transform 4s ease;
    -moz-transform: rotate(360deg);
    -o-transition: -o-transform 4s ease;
    -o-transform: rotate(360deg);
    transition: transform 4s ease;
    transform: rotate(360deg);
}  
</style>
<script>
function barrel_roll() {
    $('body').addClass('barrel_roll');
  setTimeout("$('body').removeClass('barrel_roll')", 4000);
}
</script>

My question is, what are some other cool effects that can be done using Javascript and/or CSS?
