If you're a fan of tweaks a little out of the ordinary, then AppMosaic by ctrled may be just the sort of thing you look for. Probably classifiable as an app as opposed to a tweak, it portrays the top 200 apps (free and paid) in one elongated mosaic. It only depicts the icons, but by tapping on them, a box appears at the bottom of the screen denoting the title and its publisher/developer.
