Grizzler the dog uses Heartography to take photos of things that get him excited! Sounds weird? The concept is in fact very simple, every time the pooch's heart rate goes up, the camera system takes a photo. What's so cool is that you can easily figure out exactly what your dog loves in life! You can also figure out what he is frightened of as his heart rate will rise then too. It might take you some guesswork to figure out just which photos are the excited ones and which are the scared ones however the whole concept is just incredible. Check out the photos and promo video below to see the Heartography system in action.
