The set design here is setting off an unsettling ambiance. It appears that "David's Temple" is housed within an Engineer structure; something about the cavernous, yet tomb-like interior reminds me of this early concept art for the pyramid in ALIEN:
The Alien-creature design drawings all over the place, along with some hieroglyph/cuneiform-like designs similar to those in Prometheus, hint at something familiar,yet strangely foreboding. I don't know, this is great stuff, and what makes it unique is that this material isn't hidden behind some low-quality image, it looks professional—thus limiting too much conjecture with regard to "figuring it all out".
I am almost holding back excitement because it seems as if some of Giger's old ideas are getting a second-life here. My bias is definitely showing through, but these design elements are the reason why all of this seems so... dangerous and disturbing. Take for example the top-most image near the center of the screen in this picture:
That definitely looks like:
Maybe I'm reaching, but the images plastered all over the walls have a kind of "Giger-ish" flair to them.
As somebody else has already said, the very biological forms here look to be moving toward some state of 'corruption'. With no sign of Shaw, or hints as to what her role will be, I wonder if David is keeping her in stasis, harvesting her DNA somehow to create these beings... or, would he be using Engineer DNA to accomplish all of this?
Oh... and...
*drools*
