    Hacking CSS is a great challenge and can lead to interesting results, I've reignited my interest thanks to sirdarckcat and Thornmaker who have done some fantastic work. I wanted a way to do animation and loops in pure CSS and I think it's sorta possible using meta refresh. I know meta refresh is slightly cheating but c'mon I've not got much to work with :P The technique works by specifying multiple redirects at different intervals and uses the CSS target property to simulate the animation. Check out the demo :D
