Good evening.
So to preface, i don't know that what i'm about to post actually means anything. But i'll post anyway... maybe somebody will see something in the images.
While scanning things tonight i noticed that the obelisks always light up on the same side, so you can tell which way the obelisk is "facing" by looking for these features:
A crack on the left most triangle, and divots at the tops of the middle and right triangle. Out of curiosity, i went through a bunch of the groups and mapped out which way the obelisks were facing. I was in a PG when i did this, one other cmdr in the instance.

cluster b has the same layout as e, just rotated.
Like i said, it probably doesn't mean much. Somebody probably just used some kind of template to lay out the game objects. But who knows. I would have mapped out the other clusters but i need to go to sleep or i'll be a very angry cheese at work tomorrow.
