Barrel

Barrel

       Barrel is a app from cydia that lets your sliding screen have 3d effect. Barrel offers a visual tweak to the way the icon pages are stacked and displayed. Unlike the normal mode where the icon pages appear to be placed side-by-side, Barrel offers a 3D-cube effect to these icon pages. Swiping across the several pages of homescreen icons will display each page as a side to the cube. Some of the transitions include: inside 3d cube, outside 3d cube, whirl, fade, vertical scrolling, and scatter.
