I was going to direct you to a video tribute to Firefly that I posted back in August, but it's not available anymore. Shame, it was a good one, too.
Thanks for posting these, I hadn't realised how many tributes there are.

Wish I could find it somewhere else, but there is not much to go on, just the dark image of Shepard.
