Animatabler is a plugin that adds effects when opening/closing windows of Cocoa applications.

Check out this demo:

What you'll need to do:

Download and install SIMBL (Smart InputManager Bundle Loader) if you don't have it already.

Download Animatabler here, and copy it to this path: ~/Library/Application Support/SIMBL/Plugins/

To configure this plugin, you'll need a .plist file in your OS X preference folder. You can download mine here. Just copy the file to this path afterwards: ~/Library/Preferences/zom.zumuya.Animatabler.plist

Settings will be reflected when you restart an application.

How to change the animation type:

1. open the plist file with a text editor or Pref Setter

~/Library/Preferences/zom.zumuya.Animatabler.plist

2. change the strings for keys, "ATAnimationNameWhenClosing" and "ATAnimationNameWhenOpening" to the animation name that you like.

Animation names:

* rotate
* smallzoom
* largezoom
* slidingzoom
* wrinkle
* roundedsmallzoom
* roundedlargezoom
* bend
* push
* random
