Cappuccino - animated segment controller

I was trying to implement segmented controller with Cappuccino extension. I've succeeded to make CPTrackingController work. But it seem that LPKit is better than mine. It works with animation effect. The working example is uploaded at github. (http://github.com/jaigouk/Cappuccino_merb-visual-api_ui)

LPKit enabled Cappuccino toolbar from jaigouk on Vimeo.
