Object dock swing effects in Flex rotate effects

Object Dock software has two effects, the zoom and the swing effects. The zoom effects is what I had posted last time, and now I just finished the swing effects. Not actually the swing effect of 

object dock, but it's just like one.

Actually, what I have made was a rotate effects of Flex on mouseover. You may have a look at my work below.
