I keep half-expecting the logo to get wiped out by Africa the last time the globe goes around, and apart from the disappointment when it doesn't, this is a masterpiece.
The one thing that I would consider in the nature one is the speed of the globe. It looks to be going a little fast to me, but maybe this is because the textures resemble the earth more so that the alternatives.
Agreed. The speed works just fine on the "red planet" idents, promos etc. but it seems unnatural when you use the satellite imagery.
Of course, what do I know? I'm an Aussie.
