ActiveDock is a new tweak developed by Filippo Bigarella and designer Surenix that will allow your iOS dock to look and behave like the Mac OS X Mountain Lion dock.
ActiveDock will therefore change the appearance of the usual iOS dock so that it corresponds to that of the glass of OS X Mountain Lion. Additionally, application icon reflections have been changed to mimic the OS of Apple computers.
You will also see a light bar appear below the open applications and in the background on your iDevice as on Mountain Lion. Finally, when you receive a notification as a message, the application icon will start to hop. Of course, you can choose the frequency of twists and turns (continuously, every minute, etc.).

For those interested, ActiveDock is available at the price of $ 1.99 on the BigBoss repo. It is compatible with iOS 6 and iPhone, iPad and iPod Touch.
