One of the most popular jailbreak tweaks of all times is Barrel. If you don’t know, it adds an feature to your home screen that changes the animations you see when switching between pages. A new tweak Cylinder hopes to dominate Barrel and its high price of $3.99. Currently, you can get it for free by adding this repo
and installing the Cylinder package. Not only is Cylinder free, it claims to have a better 3D effect. Currently it is in beta so its options are limited. Judging on the high piracy rates Barrel has faced there is obviously a demand for such a tweak.
