this is something that started as a pretty small idea (a pool of toxic waste) and just kind of grew from there, gaining a tank, pipes, and eventually a walkway. This is different from "Area 51a" in a lot of ways: a) This one had no real plan, Area 51a was planned from the start, b) Area 51a is more playable, more flat surfaces and stuff, and c) Area 51a was just plain cooler.
That being said, I'm still happy with this, and I had some fun doing it!
As usual, better pictures
