Gorilla cam: A simple solution for capturing amazing animal footage

A photographer has used his humble iPhone and a whole lot of ingenuity to record impressive footage of animals which even David Attenborough would be proud of.

Mark Rober says that on a recent trip to the zoo, he noticed how desperate people were to get the attention of the gorillas so they could get a photo.

That's when he hit upon the idea of using the screen of his iPhone to let the animals he was filming, to see themselves… and sure enough the idea worked.

In fact it worked so well he went on to produce a 'Gorilla cam' -- consisting of a  iPhone mounted behind a mirror with a hole cut in it -- to get some even more impressive footage.
