Ostium Screen Splitting Animation For Notification Center Features iOS 6 Support, Custom Wallpaper, ‘Gangnam Style Mode’ [Cydia Tweak]

Ostium is a somewhat unfortunately named Cydia tweak that modifies the way the Notifications Center pane opens in iOS. Ordinarily you pull the pane down from the top of the screen. With the Ostium tweak installed, you can split the screen in half with two fingers–like a pair of automatic doors, with the notifications center appearing in the middle.

Ostium is a tweak that affects the Notification Center pane’s animation.

You can decide whether you want to use either the standard Notification Center gesture or the two finger spread gesture from Ostium’s settings. With the latest version, there’s also a wallpaper setting, so you can change the way the blank space behind the Notification Center looks, if you choose to have both Ostium and the Notification Center’s slide down animation effects running at the same time.

When you have both the animations running together, it looks like the Notification Center is an elevator, so you shouldn’t be surprised to hear that the developers snuck in a Gangnam Style Mode into Ostium. You can activate this mode by double tapping on Ostium’s background wallpaper preview image in Settings. With Gangnam Style Mode active, whenever you open Notification Center, you’ll hear Psy shout “oppa gangnam style!” It’s a nice touch.

Ten points if you make this your background.

You can find Ostium in the ModMyi repository on Cydia. The tweak costs $0.99, but works on the iPhone. iPad, and iPod Touch, and even supports iOS 6 if you have an older device that supports the tethered jailbreak.
