GameDev: How to Implement a “Camera Shake” Effect

In modern videogames, a camera, or "screen", shake can add some really nice aesthetic touch and tactility to your game at a very low cost. When I went to research some concrete implementation details, however, I failed to find many examples to guide my efforts. I decided to venture forth and write up a quick article on how to do so for most 2D games. Towards the end of the article I will touch on how a camera shake might be implemented in a 3D environment. Onward!
