I just watched this underwater nature program that showed these amazing creatures that live so deep there is no light so all have these funky ways of lighting up - one even had red dots of light appearing on it's membrane that changed pattern as if it was talking.
It made me feel as if I was watching a computer generated programme it was so off the wall.

Sorry that wasn't really a reply to your question - just popped into my head when i saw your question. probably a statement of how much of that we do see nowadays.
Good to see though that nature can be more off-the-wall than most computer programmers!
