How does google do the barrel roll?

Question

If you Google, 'do a barrel roll', the whole page does a 360 rotation. Does anyone have any guesses as to how Google is doing this? I disabled javascript, and it still occurred, so maybe a css rotation?

Answer 1

If you look at the css code :

body {
    -moz-animation-duration: 4s;
    -moz-animation-iteration-count: 1;
    -moz-animation-name: roll;
}
