Before falling asleep last night I had a great idea, or so it seemed at the time. I was thinking about the ages of planets and how plate tectonics evolve over huge lengths of time, just like Pangea evolved to the continents on Earth today. I might visit a certain rocky planet again, years later, yet it has not developed as it would have in the natural world. Since I've been playing around with converting videos to gifs, I thought it would be cool if the texture maps for the planets were actually moving pictures rather than static, that could be used to create the 3D mountains and rivers and such, but over millions of years they would spread apart or sublimate under one another just like on Earth. Of course you'd need data about how plate tectonics create the surface of a globe, how that relates to mountain formation, where they spread apart as great cracks in the globe, etc. It would be hyper-realistic and would add a large amount of realism to an near perfect program already. However, I realized since you're able to land on every object in the game, using anything but static pictures would require re-writing the entire engine. Or it could be as easy as generating a gif rather than a jpg. The gif wouldn't be actually used directly as the texture map, it would be to the side and based on the year a certain frame from the gif would be used to substitute the jpg texture map. Just a random sleepy thought.
