Hidden Feature in Google Earth Sky

Yesterday I discovered an interesting "feature" (I would call it a bug, except it is cool) in the new Sky feature of Google Earth 4.2. You can fly yourself outside the "universe" and see how Sky really is just Google Earth turned inside out. When I realized that unfortunately the SpaceNavigator doesn't work with Sky, I decided to try the seldom-used feature called "G-Force" which lets you navigate in GE by flying (with the mouse or other controllers like a flight simulator yoke). Only, this mode was not intended for use with Sky. It instead transports you outside the "globe" of the sky and shows you the "universe" looking inwards. Here's how to do it:

Load up GE 4.2 and switch to the "Sky" mode (using the button in the upper center, or the menu "View->Switch to Sky"
Hit the "Ctrl" and "G" keys together - this switches you to G-Force mode and you will see your mouse cursor switch to a little airplane
Click once in the sky view and your view will go blank and/or show the globe of the sky
Hit "Ctrl-T" to switch back to normal mode and try moving the sky (zoom in and out to help see it). You should now see the sky as a "globe" as shown in the screenshot above. Things don't work normally, but its pretty interesting.
To fix things back to normal, you have to switch back to Earth view, or close GE.
