Question about "Screen Preview"

[Galactica_Actual]

LauncherPro boasts a feature known as "animated screen preview" like that in HTC Sense. I have no idea what this is, I've never used an HTC phone.

I can't find anything in the forums and when I activate it I don't notice any difference at all except my dock goes away. I'm just really curious about this, can anyone help me out?
Thanks

I believe that it shows a preview of all your home screens in small boxes.

it's like Mac's expose feature, google youtube and you'll see many examples.
