Walker Young of the Taiwan 360 VR Panograph blog has used our tutorial on creating panoramas in Google Earth for his view of Taipei in Taiwan.
Interestingly he has used a Four Seasons to create the clouds above the city. Four Seasons allows the user to replace the sky in images using the 'magic wand' tool.
There are a number of cloud settings as well as the option to place the sun/moon in the image.
