Lynx in Australia has launched a new OTP/microsite that takes the user through a series of websites (although it's really just one faux site) that links in to the next site and so on... It's been very well produced and has mini game elements throughout the play-through. I remember seeing a great execution for Lynx shower gel a while back which was a story about a dude who gets kidnapped by hot chicks and you need to decide the path at the end of each section. I did really like it and watched it all the way through. Take a look.
