Animations are a very showy type, simulating acceleration so far we thought that only worked in Mission Control, OS X Lion Expose.

However these days I discovered that this kind of animations are also available on Launchpad. To enable this kind of transitions you just have to press "Cmd + M" in the Launchpad interface, and to disable them you only need to press again the same key combination.

The negative part of transitions is the amount of resources required and also are not a definitive role so they might have stability issues and some bugs [OS X Daily]
