Viewing QTVR is awesome and CubicNavigator makes it doubley awesome by taking it to the next level - ultra smooth panning. What a treat to look at all the beautiful VR's the developer has bookmarked for us. Bookmark your own favorites!

This is a real gem and the developer is very responsive and proactive. Try it (even if you think you don't need it) and see for yourself what fun this is.
And yes, if you make 360 vr's this is a must have for testing your equirectangular images prior to assembling.
