Can anyone tell me what type of effect would be used to produce the sound used at the start of this song by Muse?

I know Muse you all these crazy computer generated effects, but I know some of you people have equally crazy ideas...and I'm guessing there's a way to make it sound vaguely similar.

So yeah, thanks.
