What a difference 2.2 billion seconds can make

Here is a fascinating video of a woman aging 69 years (2.2 billion seconds), speeded up 200 million times so the whole process appears before your eyes in less than a minute.

This animation was created using a series of eight photographs, that were taken over the span of a woman's lifetime. A set of images, called key frames, was created from these photographs to show how she looked at different times in her life. The key frames gradually transform from one to the other through a process called morphing.

There are other amazing videos in their gallery (Playing With Time). Here's one showing changes during a pregnancy.
