Some jailbreak tweaks serve no purpose as far as productivity or utility is concerned. Some tweaks are simply made to show off to your friends and family. ShakeAnimation fits squarely into this category. This isn't a tweak that you purchase to gain additional functionality on your iOS device. Instead, it's a tweak that you install solely to show off what you can do with your device.
As its name states, ShakeAnimation allows you to gain several different animations on your device with a simple shake. There are quite a few animations contained within the settings, and you can invoke them in a variety of areas such as the Lock screen, or Home screen. Talking about it can only tell you show much. For a tweak like this you really need to visualize it to get the full gist of it. Take a look at our video inside for a full visualization of ShakeAnimation in action...
