Will Burrard-Lucas, a wildlife photographer in Africa, has conceived something he calls the BeetleCam Project.
Simply put, he built a remote-controlled buggy on which he could mount a DSLR in order to get "unique close-up, ground level photographs of African wildlife".

Very cool indeed.
I wish I had one of those when we were recently in Africa. It would have been fantastic to plant a camera right in front of a leopard and get a wide-angle shot from the ground.
