Meet Danielle. She transforms from a young girl to an old woman right before your eyes, but you hardly notice.
The video was created by filmmaker Anthony Cerniello, who revealed on his Vimeo page that "Danielle" is not a real person.
"The idea was that something was happening but you can't see it but you can feel it, like ageing itself."
However, you would be surprised to know that Cerniello shot the raw footage for his five-minute short film over a short time.
He was invited to his friend Danielle's family reunion last Thanksgiving and he brought still photographer Keith Sirchio along, said website io9.
Cerniello and Sirchio shot portraits of her youngest cousins through to her oldest relatives with a Hasselblad medium format camera.
Then each photo was scanned with a drum scanner in New York and the family members that had similar bone structure were chosen.
Animators Nathan Meier and Edmund Earle were then brought on board to work in After Effects and 3D Studio Max to morph and animate the still photographs.
Finally 3D visual effects software Nuke was harnessed by artist George Cuddy to smooth out small details like the eyes and hair.
The end result might be slow-moving, so slow that you might not see the apparent ageing unless you look away for a few seconds.
This emulates ageing in real life; how we notice after five years how our parents have aged and children grown up so much.
