I figured out how he added the animation, he added the information in the scratchpad: http://www.khanacademy.org/api/labs/scratchpads/5352006906019840

He added this: http://www.khanacademy.org/cs/animated-screenshots/5352006906019840/5724160613416960.png

The only way to add an animation program would be to hack the code.
