Amusing little occurrence: playing around with different dates and movies, I got one where the still (from Love Actually) was of a different movie the characters were watching in-universe (Titanic).
I'll admit that it wasn't immediately obvious what it was, but after filling in the form and picking a movie I was very familiar with, it really gave an idea of 'where in the movie' I currently am.
Kudos to whoever created it. Very creative and interesting.
By entering your birthdate and your expected life span, it projects how far you are into your life by display an image from a movie at that same point as you are at your life today. So if you are 50% through your life, it will pick the 50% point of a movie. Ideally its a movie you know very well otherwise it won't make as much sense.
You enter the age you expect to live, your birthdate, and a movie (pick something you are very familiar with). Upon submission, a single frame of the movie is shown representing today in your life if the runtime of the movie spanned your entire predicted lifespan.
well, that's a percentage!
