3d animated flash buttons

I’m looking for tutorials or guides on how to make 3d animated flash buttons. i want to learn how to make buttons that are like what you would find on this site: http://www.flashbuttons.com/

the one that really gets me is the “cubic” one in the middle, how the little cube jumps out at you and spins.

does anyone know of any other sites that offer tutorials or anything for this type of stuff?? or know how to make them??
