This would probably be really hard to add to the game, but the idea is there would be Tetrascapes: An area where space and time don't really make too much sense, and are knotted and frayed like a rope. This would have the effect where you could walk into a room larger on the inside than on the outside, walk out of a room and end up coming back into it, find copies of yourself in the past (No interaction between player and these, apart from things you did in the room in the past, which will repeat), stuff like that. This would be useful for puzzle zones, where you have find a way to move through the area that opens the way for one of your future copies, or make really confusing dungeons. (Cookie to anyone who gets the reference in the title.)
Sounds really complicated to add to a Procedurally based system... but the whole "Larger on the Inside" thing seems like something that would totally be possible in the Sci-Fi universe of Starbound. I could imagine a drop-pod coming down and bringing a box that's barely large enough to walk into, but on the inside is large enough to hold an entire research laboratory.
I feel like this would be a wondrous experience to have in the universes. Maybe a way for them to add this is if a planet's type falls under the percentage of this biome, it has completely random sections. The transition between them would have to be almost a very small loading screen, and potentially having a doorway-like feel. If they do manage to go through with this idea, it would be interesting to have almost all of the animals in a world be affected by it as well, but have 2 or 3 that are not. Such as cockroaches that aren't a problem when in a normal sized and bigger, but are a huge problem if the area shrinks you down to smaller than them, or foxes in a similar situation.
