Kirupa.com tutorial "load random movie"

hi, great tutorial by the way, thanks kirupa.com

this is the code for that tutorial…

[SIZE=2]filename = [“circular.swf”, “vibration.swf”, “random_movement.swf”]; path = “http://www.kirupa.com/developer/actionscript/animation/”; i = filename.length; k = Math.floor(Math.random()*i); loadMovie(path+filename[k], movieTarget);[/SIZE]

just one thing…the same effect WITHOUT reloading the page
that is to say that the movie randomly changes over time

hows that done then?

also, is the time frame between the new random movie tot replacing
the old movie er, setable (if that is even a word)

thanks for any help
