Animation images. Heart beat.

My objects have been compared to a hear.
I decided to create a stop motion video using 2 images.
I will be illustrating a heart beat that changes.
I will edit the sound myself and take the sample form one of the free sound libraries.
The video will be approximately 2/3 minutes long Heartbeat.

The images i will be using for the animation.

In order to better understand how the hear moves.
