If you haven't yet seen/heard the Symphony of Science videos, you should really check them out. They consist of some of the best, if not only, auto-tuned Carl Sagan clips set to synth music you will ever see.
I particular recommend this one and this one, though they are all outstanding. I find myself continuously surprised at how much completely missed what a fox Carl Sagan was, though I probably hadn't seen many of these clips from Cosmos since I was about five.
