As mentioned in the description, the background is always in motion, disconnected from the rest of the game. This effect can be achieved in at least two ways:

  • Using the straightforward approach, we can just move a huge textured polygon (or any number of polygons) in the background. Creating seamless looping animation in this case may require a bit of work.
