Animation on a preloader

I have a question about a different kind of preloader:

I´d like to make a preloader with an animation instead of a loadbar simply.
I made a MC with an animation and this should play more as the main movie is completely loaded. Like steps of a person on a stair. Each step is a 10% completed loaded part of the main movie.

Thanks of any help…
