Heliopolis

I haven't seen anything like the lonely triangle in your first example before. Pretty neat! Nice and strange textures, overall, too.

Generic contribution:

I don't know the internal workings of this generator but I was attempting to provoke weird outputs by altering the colors parameter to things like -0, 1.2, 5-3, 3(3), *, etc. Like I said I don't know how its scripted so for all I know any non-(positive)numerical input could default to 3.
