iPad flip-clock with Core Animation

I'm trying to make the flip-clock animation, I find this tutorial very interesting http://www.voyce.com/index.php/2010/04/10/creating-an-ipad-flip-clock-with-core-animation/ but I still can't make it work. If someone did it and could share is experience or even the code source that will be really nice.

Thanks,

P.S: if you have other tutorial link please share them.
