From the site description:
If we started a movie on the day you were born, and stretched it over your lifespan, this is where you'd be in that movie. So if you're a teenager, you might see Luke arguing with Uncle Owen, or Cameron making a phony phone call to Ed Rooney. If you're a retiree, you might see the Marshmallow Man, or Toto pulling away the curtain. And if you're in your mid-thirties, you might be relieved to know that Ferris is still eating lunch, and the Millenium Falcon hasn't left Tatooine.Go here to try it yourself: Where Are You in the Movie?
