I saw someone with a Macbook Pro using the Spotlight feature several times, and every time the Spotlight opened, it used a certain effect that's not like what I see in other Macs (I use Leopard).
The effect I'm talking about is like a vanishing "teleport" effect, it opens up starting with a thin, long horizontal bright line which shortens and expands in height until it reveals the Spotlight. To see a similar effect, use a recent version of Safari with several tabs open, and drag one of the tabs down as if you're going to break it off into a new window.
Does this effect happen to be OS based, or exist from a third-party tool (Something like Compiz, but for Mac)?
