Legendary British nature documentary maker David Attenborough (you may be familiar with his work if you saw the groundbreaking and epic Planet Earth has developed an oddly effective new way to film his favourite subjects - reclusive wild animals - in their natural habitat.

For his new program, Tiger - Spy in the Jungle, currently showing on BBC1 in the UK (and no doubt in America and the rest of the world soon), he got exclusive footage of tiger cubs, and was able to follow them from newborns to adulthood thanks to an inventive new filming technique. Trunk cams.

Yes, somehow Attenborough and his team got elephants to film the action in India's Pench National Park, using cameras made to camouflage with their trunks. (I swear this isn't an April Fool).

You can read more about this revolution in nature documentary making here, but I still don't understand how the elephants were persuaded to participate. I hope they at least got union rates.
