SCI FI :) Actually factory backgrounds...the dark sky smoggy looking ones like in London, Buffalo, and old Pittsburg... Stacks, refineries, etc etc... I'm feeling down today... City street type are probably always good...and of course the cow pasteur variety :)

Humankind has not woven the web of life. We are but one thread within it.
Whatever we do to the web, we do to ourselves. All things are bound together.
All things connect......Chief Seattle, 1854
