Can this be updated for infinity animation?

Something like this:

@-ms-keyframes rotate {
    from {
        -ms-transform: rotate(0deg);
        transform: rotate(0deg);
    }
    to {
        -ms-transform: rotate(-360deg);
        transform: rotate(-360deg);
    }
}

.rotate {
    behavior: url(ms-transform.htc);
    -ms-animation: rotate 800ms linear infinite;
}

It's a good idea. However older versions of Internet Explorer (<IE10) are well forgotten and I haven't spent any extra effort on this project after that.
