A guy used his iPhone and a mirror to get some really cool footage of monkeys and gorillas at the zoo in "Today's YouTube Treasure". I think this is really great because I never would of thought of any of this. The guy decides he could get the monkey's attention by showing them, themselves and he was right. Then he drills a hole in the mirror and puts the iPhone camera in the hole so the primates can see themselves even bigger. Take a look.
