A few simple ASObjC scripts demonstrating the usage of various Cocoa classes.  These should be saved and run as stay-open applications, since GUI elements need to be run on the main thread, although many* can be run from the **Script Editor** or **Script Debugger** (and adjusted for **Xcode**, of course).  Care should be taken when running from an editor though, as programmatically created objects such as windows and menu items can be added to the current editor instance, in which case they will be kept until they are explicitly removed or the editor is quit.
