Apart from the incredible OpenGL'ed browser aspects of CubicNavigator, it serves a purpose in the standard VR panorama workflow. Flattened equirectangular images can be drag/dropped to preview as a fullscreen cubic QTVR before committing to final edits and conversion to cube faces (see the developer's CubicConverter app). It also opens up for smooth viewing of truly high resolution VR panoramas. The budding integration with tours produced by CubicConnector, another one of the developer's apps, looks very promising for big wow-factor presentations. The 3D tilting of the map and the angle-of-view cones, all canned effects, already appear impressive. I am frankly amazed at how this small(?) Australian developer showed Apple how VR can be done. Respect. The $20 price redefines the term "bargain."
