Space Lab 4.0

I like Science Fiction. However, most of the pictures one can find are very "human like". A friend asked me "what do you think an observation deck in an alien ship would look like?" My answer was "very alien!"
If at all, one could perhaps find some parts that may remind of our human culture and technology. However, there is a high propability we would not even recognize the aliens themselves when we meet them. Not to speak of their advanced technology.
To give some orientation I implemented some (human-) kind of floor and ceiling.
