Photographer Chris Bray explains:
After my clients had finished photographing this adolescent male lion in Kenya beside the road, I taped a GoPro Hero 2 onto a $60 radio controlled car, and drove it slowly towards the lion. As soon as the lion saw it, it locked right onto it and paced towards it, came right up to it, gave it a few paw swipes (claws in, so only curious), and then started to maul it, at which point I drove the RC car forwards and backwards in the hope the lion would let it go rather than either destroy it or run away with it.
