Thought about that, but it would be much funner if US2 recognized some objects as organisms and they could experience the real effects of space. Also my sister just became a brony. Last night, she stayed up from around 8:00 to 12:20 watching MLP FiM. But. I have to say, the plots are good but I certainly don't like everything else, except for maybe the animation engine, which is the best I've seen in a while. At least, compared to Arthur Season 16-17 animation. But at least Arthur is still around, right?
Possibly have microscopic stuff? Like sand grain, water droplet, ant, water bear, Thiomargarita Namibiensis (largest bacteria in the world; visible to naked eye), salt grain, dust mite, airplane, Washington Monument, Giza pyramid, Eiffel Tower, that kinda stuff.
