Here's an idea I had after reading some of the posts about Doomsday predictions regarding the Large Hadron Collider.
What if we made our own "Timeline", of predictions that were made by prominent doomsayers, and have already failed? The LHC has been the object of many, and Ivan Stein's series of videos (http://www.youtube.com/user/timeline2012) has some great ones.
