Recently, i saw a show on discovery called "time warp" and was amazed by it. They basically have cameras that take 5k frames per second of a little bit of everything, then play them in slow motion. Below is a link to a nice collection of videos: http://www.quoted4truth.com/articles/12-awesome-slowmo-videos
well it is common enough if you see sports i mean. they take frames at the same rate and then play it real slow.. golf, cricket , hockey(not ice hockey)....
