21st century fox textures

Hi

I saw some videos on youtube showing a modified version of the 21st century fox intro.

does anybody in the US maybe have an idea were you could get the ground and sky texture from?

I tried finding it via google without any luck.

I think they might have done a frame by frame from the legit one.

Well the one I posted is probably a frame by frame since it is for Simpsons.

This one is very close: http://vimeo.com/1393328

I cannot look up more on Google since the server seems to have a high amount
of internal errors today.

But the ground plane image and backdrop feature a similar detail and color palette.
Those must come from somewhere.
