wow atagert you completely read my mind about using the earth at night texture. I wanted to somehow merge a night and day texture and have a line of sun sweep over the earth changing day to night. I have no idea how it would be done, but I know there is a way to make textures and materials change over time. I think it's called procedural textures or something. Not the slightest clue how to do it, but maybe there's some tutorials out there...?
With my Pixar test I actually have no plans on replacing the Pixar lettering. As you said anything I did along those lines would only work for theaters with an "I" in them, but the .blend is designed such that the "I" is a mesh while the "P XAR" is plain text, so anyone could use my file and simply replace the lettering if they so chose.
I've actually had a number of ideas of what to do with the animation, but nothing has fallen into place yet. I want the first portion of the animation to proceed exactly like the regular pixar animation, but something different to happen at the end.
Example ideas: Luxo hopping on the letter "I" acts like an air pump, blowing up a balloon with the theater name on the side. Or perhaps the I drives a flame like in a hot air balloon, which blows up the above mentioned balloon. On another whole train of thought, the I could be connected to some kind of fuse, and when it disappears into the ground it "sparks" lighting the fuse, which snakes across the ground and eventually explodes... something? LOL like I said I've got ideas, but for now the focus is just to finish the original Pixar animation (which only lasts ~10 seconds btw) and release the .blend file for people to tinker with. I'll then move on to animating a cool ending, and again release the .blend file hopefully with easy instructions that people can customize with. It all depends on how much time I get to put into these silly projects
