How do I achieve the Sumobooth effect

All
Can anyone help me understand how the Sumobooth developers were able to achieve the skin flapping effect; I want the skin to flap like in the Sumobooth app (http://www.youtube.com/watch?v=6v2xwvKq50I) for an app I am developing in Corona. Any ideas?

Thanks,

Basically I want the skin in a picture to respond to the touch event… [import]uid: 13905 topic_id: 8059 reply_id: 28700[/import]
