Click and drag with your mouse to rotate Linda's tummy (at 25 weeks) back and forth. You'll need QuickTime installed on your computer for this to work.
(If you don't feel like instlaling the QuickTime software, you can check out a black-and-white animated version of the tummy images.)
You can see the same thing at eight months here.
