Sphereful (Composition by smokris)
Sphereful is a viewer for equirectangular panoramas, written as a QuartzBuilder application.
Drag-and-drop an image onto the application window, then drag with the mouse, or use the arrow keys, to navigate.
The final QuartzBuilder application is also attached (since the composition isn't too useful inside the Quartz Composer Editor), along with a sample equirectangular panorama.
