This creative choose your own adventure video on YouTube, by SpecBox, has combined indie short films with the power of YouTube annotations.  The plot of the short film is simple.  An online gamer is obviously obsessed with a certain online role playing game.  It is up to you to choose how you would like to see the destruction of his computer play out.  I do hope there are more films like this from SpecBox or other creative YouTubers to make videos more interactive.
