SwingOSC is an OpenSoundControl (OSC) server intended for scripting java(tm), such as to create graphical user interfaces with AWT or Swing classes.

From the SuperCollider perspective, SwingOSC provides a substantial set of classes both on the client (sclang) and the server (java), that allows you to create user interfaces. The classes are based on the original cocoa (Mac OS X) GUI classes in order to facilitate the switching between both GUI kits. Using the GUI abstraction class allows you to write GUI code that runs crossplatform and can use cocoa GUI on Mac OS X as well.

SwingOSC is however more powerful as it allows you to bridge SuperCollider and Java, easily adding custom components (GUI or other) from your own or other people's java classes.
