customized animation

Is there a program for Windows and Mac?

when I was messing around w / a Mac to a shop i saw that when I minimize or program that was an animation different from my Windows computer. I wondered if there was a program that could put Windows on my computer to allow me to customize this type of thing.

If you mean the dock at the bottom is here for Windows: http://rocketdock.com/ icons are on the same link.
