All I had time for last night was wiring up a bunch of patches, hoping later today I'll be able to get at least LDS built (since it's fundamentally easy, just a huge resource lift).
Here's a cool shot of an iron and copper mine next to each other - it's even more notable without night vision equipment in, but then it's too dark basically everywhere else. I'm definitely committed to using colored lamps in future saves - I like the ambiance they give.
