I dig time lapse photography. I was pleased, then, to check out this awesome (and popular) 20 second video:
I took a series of photos every other day as my wife was pregnant with our first child. Watch the belly expanding fun! Visit the URL above for more info.
It’s quite amazing, and a fantastic shorthand illustration of what happens to a woman’s body as she moves through her pregnancy. There’s lots more information at the Gestation Project website.
UPDATE: In case you’re wondering (I was), the music is Joan Osborne covering The Band’s “The Weight”.
UPDATE #2: Colleen and Triviaqueen emailed and Jessica commented and suggested this other, cool timelapse video.

Then I read that in bloglines it took me a moment to realise the “I took a series of photos” was a quote and I was about to congragulate you and Julie. 🙂
That was neet. I saw another video earlier today using time lapse photography of a womans face. She took a photo every day for the past three years. It can be seen on Dennisbullock.com
Thanks for sharing.
Wow, how neat! (and also, how scary that it’s going to happen to my body in the next few months)
