What is "snorricam"

A SnorriCam (also chestcam, bodymount camera, bodycam or bodymount) is a camera device used in filmmaking that is rigged to the body of the actor, facing the actor directly, so when they walk, they do not appear to move, but everything around them does. A SnorriCam presents a dynamic point of view from the actor's perspective, providing an unusual sense of vertigo for the viewer.
