Therefor it shows only what it has so far and does not wait for the image to complete, leaving a noisy image. If the camera would stay steady for a little longer you'd be able to see the image converge.
I might be wrong at some points though, since I'm not an expert on this stuff :P
Never went any further then a simple ray tracer (with help from a small series of tutorials which are written by the uploader of this video, if I'm correct).
The noise is caused by the rendering technique that this video demonstrates. It is called path tracing, which is a very computationally expensive process to approximate real life lightning. It involves tracing light rays from a light source to a random direction where it bounces of the surface until it eventually bounces into the 'camera'.
In order to generate a good looking image, millions of these light rays needed, which is nearly impossible even on a high-end computer. Therefor

What causes the noise?
