1 {scene: Me at the computer}
2 {scene: Me at the computer, now with noticeable random pixel noise in the image}
3 {scene: Me, starting to look annoyed, at the computer, with more noise in the image}
4 Me: {in image with a huge amount of random noise} I wish the neighbours would stop making so much noise!

Noise is a term used in the physical sciences, particularly signal and image processing, to describe some sort of interference pattern that makes the desired characteristics of a signal more difficult to determine. In this case, I simply used my graphics program to add random pixel noise to the frames.
